45 th TRANSPORTATION BATTALION HISTORY, 1 JAN - 30 JUNE
I S-1 (PERSONNEL AND ADMINISTRATION)
(U) GENERAL: During the period 1 January through 30 June 1963, the
Unit personnel section carried on normal personnel activities, thirty-five
officers and one hundred ninety one enlisted men were processed for return
to CONUS and one hundred twenty-six officers and two hundred forty-two
men were processed in for assignment to units of the battalion. The overall
strength of the battalion, both officer and enlisted, remained about the
same throughout the period.
(U) CHANGE OF STATUS: During the period of this report the status of
the US Army Utility Tactical Transport Helicopter Company was changed from
Temporary Change of Station from Okinawa to Permanent Change of Station
to the Republic of Vietnam. Notice of the change was Received on 20 March
and all actions to include transfer of personnel back to Okinawa were to
be completed by 22 March. The personnel section successfully accomplished
the required actions to include preparations of adjusted DEROS's, submission
of AOR Rosters, publication of PCS orders on personnel returning to Okinawa
and arranging for transportation.
(U) TRANSFER OF RECORDS: The Personnel Section processed and moved
the records of the 81st and 8th Transportation Companies (Light helicopter)
and the 18th Aviation Company (Fixed Wing Light Transport) and attached
units to Pleiku, Republic of Vietnam. This move was made on 15 March in
Preparation for the assumption of operational control of these units on
1 April by the 52d Aviation Battalion. This action included a complete
records, finance and passport check, furnishing a thirty day supply of
blank forms, coordination with the personnel section at Pleiku in the issuance
of orders, payment and processing of personnel returning to CONUS and the
processing of incoming personnel.
(U) NEW UNITS ASSIGNED: The 57th Medical Detachment (Helicopter) consisting
of 9 officers and 22 enlisted men was attached on 31 January. Also, in
January the 19th Quartermaster Detachment (Petroleum Quality Surveillance)
consisting of one enlisted man and the 22d and 24th Quartermaster Detachment
(Petroleum Bulk Storage and issue) each consisting of 8 EM were attached
to the Battalion and further attached to the 18th Aviation Company, 8th
Transportation Company and 81st Transportation Company in the order listed.
The advanced detachment of an Air Mobile Company arrived on 23 March to
coordinate Movement and processing actions. The detachment consisted of
one captain and one sergeant.
(U) PLANS: During the period an addition to S-l functions was taken
under consideration. It was contemplated that the Unit personnel Section
would assume the responsibility for the preparation of all unit morning
reports. This change would greatly reduce errors and facilitate the forwarding
of Morning Reports to USARPAC.
(U) AWARDS AND DECORATIONS: During the reporting period approximately
913 recommendations for awards were processed though the S-1 section. These
included 796 Air Medals or OLC's, 31 Bronze Stars, 70 Distinguished Flying
Crosses, and 16 Army Commendations Medals. 496 approved awards were received
and forwarded to units concerned for presentation. These included 398 Air
Medals or Oak Leaf Clusters, thereto, 25 Bronze Stars, 31 Purple Hearts,
39 Distinguished Flying Crosses and 3 Army Commendation Medals.
(U) MORALE: Morale has been generally high despite the fact that some
enlisted men must still be held beyond their normal rotation date due to
the non-arrival of adequate replacements.
(U) PROBLEM AREAS: The major problem areas requiring early resolution
and over which the battalion has no control are:
1, Trained replacements: Time, mission requirements and the austere
personnel position of most units does not permit proper training of replacements
who arrive with little or no practical experience. This is particularly
true of aircraft mechanics, MOS 676 and 675. The slow arrival of mechanics
and the fact that a large percentage of those arriving are MOS 670 have
created a serious problem in aircraft maintenance.
2, Advance information on inbound personnel: The lack of adequate and
accurate advance information on inbound personnel created various problems.
(a) Officers: Although the battalion received advance orders and copies
of DA Form 66 for approximately, 95% of inbound officers, the actual date
of arrival varied as much as one month from, the individual's availability
date and advance information did not contain qualification in aircraft.
This precluded prior planning of the officer's ultimate assignment and
caused a considerable delay between arrival at battalion and arrival at
a final unit of assignment.
(b) Enlisted men: Advance information on arrival of enlisted men was
needed for planning purposes. Operational necessities often require the
transfer of enlisted men from one unit to another which in turn causes
new arrivals to be diverted from unit of assignment as indicated on orders.
This in turn creates an additional work load on the personnel section.
If accurate information on arrival dates was received advance planning
could be accomplished and eliminate the need for diverting arrivals and
reduce the Personnel Section's work load.
(c) New Units: Detailed advance information on arrival dates of new
units, particularly large units, was needed to preclude a serious billeting
(U) POTENTIAL PROBLEM AREAS: A problem area involving officers may
arise. This problem would be due to the fact that the majority of inbound
officers are assigned on DA orders to the 45th Transportation Battalion
with a relatively few assigned directly to units of the battalion. This
situation requires this battalion to screen all incoming officers and assign
a "fair share" to the 52nd Aviation Battalion. This is not the ideal solution
but is the only course of action deemed practical at this time. A recommendation
is now being prepared for submission which, if approved, would require
that Department of the Army amend a certain portion of existing orders
to divert officers to the 52nd Avn Bn.
(U) ORGANIZATION: During the reporting period there were two personnel
assigned to the section for duty. The Assistant S-3 performed as S-2 as
an additional duty. The Intelligence Sergeant was assigned 3 January 1963
filling a vacancy that existed for 8 months. Later during the period a
full time S-2 was assigned to the battalion as a primary staff member with
the additional duty as communications officer.
(U) MEMORANDUM: On 2 March 1963, a memorandum pertaining to physical
security was published and distributed to all units, to be used by the
commander as a guide line in establishing a physical security plan for
his area of responsibility. A memorandum was published on 6 March 1963
outlining a uniform procedure to be used by units within the battalion
for the proper handling, reciting for and storage of classified defense
information. In May 1963 the responsibility of physical security of installations
was assumed by the S-3 Section however no additional revisions were made
on the previously published memorandum on physical security issued by the
(U) COMBAT INTELLIGENCE: During the latter half of the reporting period,
a combat intelligence function was set up in the battalion war room. 1:
lOO,0O0 scale maps of RVN III and IV Corps were posted daily from ISUM's
received from the respective corps. A major limitation of the combat intelligence
section was the lack of rapid and secure communications with Corps Advisory
Groups. This situation seriously limited the transmission of timely information
to the S-2 Section for ultimate distribution to the operational units.
Towards the end of the reporting period plans were made to integrate the
S-2 Section as an aviation intelligence center with the III Corps Advisory
Group. A detailed operations plan was written which was enthusiastically
accepted by all of the subordinate units. A target date of 15 July 1963
had been set to have the plan in full operation. By integrating the S-2
Section with the Corps Advisory Group it was felt that many of the communications
problems in our combat intelligence capability would be greatly expanded.
(U) PERSONNEL SECURITY: In the personnel security field, the problem
of having security clearances validated by US Army, Ryukus Island, arose.
The problem was administrative due to the large number of replacement personnel
arriving during the month of December 1962 and no one to process the applications
for validation. This problem was solved by the assignment of an Intelligence
Sergeant and approximately 534 security clearances were validated during
the reporting period. A close working arrangement with the personnel office
has insured that personnel security actions are initiated during processing
of incoming personnel thereby avoiding excessive backlog. There were relatively
few requirements for the processing of initial clearances due to the fact
that the majority of replacement personnel possessed security clearances
prior to their arrival in the battalion. During the reporting period 29
CONFIDENTIAL and 8 SECRET security clearances were processed.
(U) DOCUMENTS: The number of SECRET documents received during the reporting
period continued to be larger then normally received by a battalion. 383
SECRET documents were processed and 150 were destroyed. The S-2 Section
initiated a program of review, upon request of documents originated by
other sections, for proper classification of a document. Two four drawer
safes were obtained and greatly facilitate quick checks on the presence
(U) INSPECTIONS: This section was inspected by the Inspector General,
US Army Support Group, Vietnam during February and no deficiencies were
noted. On 20 February, Lt Col Jacob G. Haven, Commanding Officer of the
209th Military Intelligence Battalion in Okinawa and Captain George E.
Marine, G-2 Section, USARYIS, inspected the section and several minor discrepancies
were noted, one being that the units were not briefing newly assigned personnel
on applicable security directives, a suggested security briefing was extracted
from a US Army Support Group, Vietnam directive, published and distributed
to all units. During the month of June, an Intelligence Corps Team from
Headquarters USARYIS inspected this headquarters and all subordinate units.
Conversation with personnel of the team indicated that the security program
within the 45th Transportation Battalion was considered highly satisfactory.
Subordinate units of this headquarters regularly inspected on a monthly
basis. No major discrepancies were noted and all units appeared to have
excellent security programs.
III S-3 (PLANS AND OPERATIONS)
(U) CHANGES OF ASSIGNED UNITS:

completed and distributed. The procedures set forth in this SOP are to
be followed by subordinate commands in the planning and execution of Airmobile
Operations. It is designed to facilitate the planning, coordination and
control necessary for successful Airmobile Operations.
Company and Unit SOP's will be revised to conform with all provisions
of this SOP.
(U) EVALUATION OF UH-1B HELICOPTER PERFORMANCE:
A test was conducted 22-25 March 1963 in the mountainous terrain in
II ARVN Corps, Republic of Vietnam.

IV S-4 (MAINTENANCE - SUPPLY)
I (U) GENERAL
A. New Units
1. The 57th Medical Detachment (Helicopter Ambulance) from Ft Mead
Maryland was assigned to this battalion and physically located in the Tan
Son Nhut area on 1 Feb. 63. Arrangements were made for their billeting,
messing, and operational areas, Since the battalion was programming and
furnishing considerable logistical support in the Tan Son Nhut area, the
requirements and workload impact of the unit was slight . Due t o the increased
aircraft density in this area, operational space at Tan Son Nhut was at
a premium and may present a problem in the future as the Vietnamese Civilian
and Military Airfield requirements expand.
2 Three new Quartermaster POL Detachments were processed into Vietnam
and deployed to the field. Since the previous POL Detachments had been
split, both equipment and personnel wise, equipment had to be broken down
and redistributed so each unit would have a complete set.
3. A new Battalion headquarters was processed into Vietnam and deployed
to the field. The 45th provided the following assistance:
a. Equipment and Supply requirements were determined prior to the units
arrival and requisitions submitted to obtain these items.
b. As the items were received they were trans-shipped to the new headquarters
c. Standing operating procedures for S-4 operations, and copies of
all pertinent regulations, circulars, directives, forms, etc. were furnished
the S-4, of the new battalion,
d. As the vehicles were off located from the ship, they were processed,
fueled, and prepared for trans-shipment to the final destination.
e. Rubber stamps and locally procurable office equipment were obtained
and shipped to the new area.
f. Complete briefings were given the S-4 and the Supply Sergeant on
the units of their command, local policies, procedures, channels, operational
g. In preparation for the arrival and deployment to the field of an
Air Mobile Company, these actions were taken:
(1) Determination was made of equipment, other than TO&E, that
was required. Requisitions were submitted for these items.
(2) Coordination was effected with the engineers to assure adequate
operational, maintenance, ramp and living areas.
(3) Coordination was effected with the engineers and quartermaster
on the requirements and installation timetable for major items of equipment
such as: (a) Water tanks and purification system, (b) Main generators for
the compound, (c) Refrigerators and freezers, (d) Kitchen ranges and serving
equipment, (e) Tents, (f ) Rations
h. During April 1963 the 114th Air Mobile was assigned to this battalion
and to be located at Vinh Long on the 18th of April. Tentage and essential
housekeeping equipment were set up and put into operation. This required
prior coordination with the various technical service sections and the
G-3 section of USASC,V. The first element of the 114th arrived by air on
the 7th of May 1963. All personnel were air transported to Vinh Long without
an extended stop over at Tan Son Nhut due to the lack of transient facilities.
45th Trans Bn S-4 was notified on 30 April 1963 that the ETA of the
USNS Marine Fiddler carrying the TO&E equipment for the 114th Air Mobile
Company would be 14-18 May 1963. Due to the inconsistency of water transportation
the ETA was changed approximately five times. The vessel finally arrived
on 21 May 1963, at 1800 hrs at the port.
(1) Pre Planning Stage:
(a) Coordination: The plan prepared by the 45th Bn S-4 Section included
coordination effected with and entailed the following:
1. Port Operations USASC.V: Tha S-4 Section worked closely with Capt
Shaefer, Port Operations Officer, from date first notification was given
until all equipment had cleared the port. The Port Operations Officer furnished
information as to:
a. ETA & subsequent changes
b. Customs processing procedures
c. It was determined that extra transportation was need as follows:
5-5 ton S&P's for 15 conexes
6-2 1/2 ton trucks for 40 boxes of cargo
2-5 ton tractor for 2-simi-trl shop vans
(b) Movement Plan: Work began on the movement plan when first word
was given of the ETA of the Marine Fiddler. This was on 30 April 1963.
The composition of the convoy was governed by the number of vehicles that
could be moved across the ferry at Hung Thuan Cat. An experience factor
of 216 ft of towed equipment per hour was used. Experience from actual
crossing revealed that 216 ft of towed equipment per l/2 hour is a realistic
(c) Processing and Movement from Port to Staging Area: Actual processing
again at 1020 hours 22 May 1963. Last vehicle was moved to the staging
area at 1400 hrs 24 May 1963.
(d) Operations at Staging Area: Vehicles were refueled and oiled and
final 2d echelon checks were made. At 1930 hrs prior to the day of the
move, convoy personnel were given their vehicle assignments and briefed
on the move by the convoy commander in the 45th/57th EM Mess Hall.
(e) Convoy Movement:
1. Personnel arrived at staging area 0600 hrs 25 May. It had rained
the night before and there was difficulty in moving vehicles. However,
vehicles moved out as planned. To preclude this difficulty the second convoy
was formed in the 45th/57th compound where firmer ground was available.
First convoy moved out from Cholon at 0735 hrs. Convoy Commander stayed
far enough ahead of convoy in order to block traffic on far side of bridges
enroute to My Tho to insure expeditious crossing of vehicles. Convoy commander
went ahead to meet security at IP and lead it up road about two miles on
RT. 4 to wait for convoy. This precluded congestion at traffic circle and
vulnerability to attack. Enroute two ARVN vehicles, carrying conexes, broke
down. These vehicles were towed to destination and accompanied convoy.
Air cover was late due to inclement weather. Otherwise the operation went
smoothly. Convoy closed at Vinh Long at 1315 hrs 25 May 1963. At ferry,
convoy commander visually inspected ferry capacity. It was determined that
the low bed, purposely left in the second convoy serial, could not maneuver
the bridge due to its length of 64 ft.
2. The 114th could not obtain facilities to lift conexes from ARVN
transportation. The 5 ton wrecker which would have met the requirement
was purposely left for the second convoy in order that vehicles that might
have broken down could have secured in strategic hamlets along the route
and picked up by the wrecker in the second convoy. The importance of getting
vehicles to destination undamaged or un-pilfered out weighed the inconvenience
caused in not being able to unload ARVN vehicles right away.
3. The second convoy went off without one hitch. Convoy closed at 1215
hrs, 28 May 1963. Clearance was not obtained for 27 May as originally planned.
1. On 4 January 1963, a conference on POL procedures was held at US
Military Assistance Command, Vietnam (MACV) with logistical and administrative
agencies concerned. A system to relieve the lack of POL coordination was
presented and agreed to by all present. This system was subsequently to
be presented to the operational agencies being represented. The proposed
system was discussed and again agreed to by all present. The MAAG Logistics
Division representative subsequently withdrew his agreement until a waiver
could be obtained for certain accounting requirements. On 14 February a
representative of MACV J-4 was appointed to evaluate the present POL system.
On 4 March a conference was held at US Army Support Command, Vietnam (USASC,V)
on the proposed POL system. All interested administrative and operational
agencies were represented. Again everyone agreed to the system as originally
proposed. The procedures and responsibilities agreed to have been circulated
to the interested parties, but signed concurrence have not been received
at the end of this quarter. For all practical purposes, the system is now
in operation and should reduce the requirements of the S-4 Section physically
handling POL in the future.
2. During this last quarter the following POL shipments were made:
( a) Routine Shipments:
JP4 Jet Fuel 6 Shipments 17,800 Gallons
115/145 AV Gas 18 Shipments 270,470 Gallons
MO Gas 11 Shipments 29,383 Gallons
Diesel 12 Shipments 18,776 Gallons
Oil, 1100 6 Shipments 15,106 Gallons
Solvent 4 Shipments 7,398 Gallons
Lube Oil OE30 2 Shipments 385 Gallons
TOTAL 59 Shipments 359,318 Gallons
(b) Emergency Shipments:
JP-4 6 Shipments 11,474 Gallons
115/145 AV Gas 5 Shipments 28,399 Gallons
MO Gas 1 Shipment 106 Gallons
Total 12 Shipments 39,979 Gallons
3. On 17 June a back up pumping system for refueling of aircraft on
major combat missions was put into effect. This system included 1 JP-4
hand pump w/filter segregator and 2 AVGAS hand pumps. Personnel of the
S-4 Section accompany and operate this equipment on each mission. They,
also, monitor refueling operations in the interest of expediting refueling
4. Inspection of tankers hand recited to Corps Advisors showed a great
lack of 1st and 2d echelon maintenance.
1. Throughout this period the S-4 monitored and acted as the contracting
Officer's Representative for the following contracts:
a. Packing and Crating.
b. Theatre Construction: A theatre was constructed in the 45th Trans
Bn, 57th Co Compound. The new theatre seats approximately 124 people, has
a cinemascope type screen and provides for uninterrupted film projection.
Approximate dollar value: $2,013.00. A contract for bamboo siding for 57th
theatre was completed on 13 June 1963.
c. Laundry Contract: This covers the civilian laundering of sheets,
pillow cases, mess uniforms, dispensary towels and linen, etc. for 45th/57th
Compound. Approximate dollar value: $2,600.00.
d. External rewiring: 45th/57th compound rewiring began on 3 June 1963.
The new external system will have the capacity to carry 173 KW of power.
However the present internal wiring of buildings will not be able to carry
such a load. Also, the present power source will only generate 60 KW. The
USASC,V Engineer has been made aware of these incompatibilities.
e. Construction of the UH-1 section hanger and hardstand began on 17
f. Contract for the flooring of the 45th Dispensary and for construction
of the 57th garbage shed, and the 57th wash rack was let on 28 June 1963.
2. Miscellaneous construction and repair at 45th/57th compound also
a. Installation of hot water system. Approximate dollar value: $783.34.
b. Water line installation: Approximate dollar value: $2,008.00.
c. Renovate buildings and roadway. Approximate dollar value: $4,968.04
d. Cover floors and install water line. Approximate dollar value: $2,013.73.
D. ADDITIONAL BILLETING:
. 1- Information received during the 3d Quarter of FY 63 indicated
that a substantial increase in strength could be expected in the near future.
On this basis a detailed survey of existing and required billeting facilities
was conducted. The scope of this survey included the units which are now
assigned to the 52d Aviation Battalion, The results, in the form of a classified
letter, were furnished USASC,V Engineer on 11 March. This has resulted
in awarding of contracts for construction of four buildings within the
45th/57th compound, six buildings at Bien Hoa, and seven buildings at Qui
Nhon, Requirements for buildings in other areas are currently being processed
by the USASG,V Engineers, Construction of the 4 - 7x14 meter billets in
the 45th/57th Cantonment area began the 13 April 1963. Last billet was
accepted 31 May 1963.
2. Following the addition of the new billets, there still existed a
requirement for additional housing. Letters were sent forward to CG, USASG,V
requesting additional billeting for 45th/57th compound and the 33d Compound
at Bien Hoa. Also, a letter was sent to the Commanding General requesting
the personnel of the 2d Air Division, housed in the billets of the 93d
Trans Co at Soc Trang, be relocated in facilities and the 2d Air Division
agreed to erect.
3. Also, included in the letter pertaining to the, 33d Trans Co was
a request for assistance in expediting the construction of a potable water
well and running water latrines.
A. PROBLEM AREAS:
a. In April 1962 a requisition was submitted for 17 each 50 GPM pumps.
These pumps were to be used for refueling aircraft in the field. An estimated
delivery date was received on 13 February 1963. When the estimated delivery
date had passed without receipt of the pumps a message was sent requesting
information as to the status of the pumps. On 5 March a reply was received
that the requisitions had been canceled and if the requirement still existed
to re-requisition. Action was taken in an attempt to have the pumps obtained
on a priority basis, the lack of the pumps was causing refueling of some
aircraft in the field by hand pump. This was time consuming and hampered
b. The distance and time element required to transmit information and
requirements between the field units and the US Army Support Group, Vietnam,
and Okinawa, was too extensive to provide timely support.
c. Construction and Service type logistical support is still extremely
limited. Once requirement exists, it must be processed through channels
until it is approved. Then it is sent to the Purchasing and Contracting
Office for advertising, bidding, negotiations and the signing of a contract.
This is extremely time consuming and frequently detrimental to morale when
the items involved are for messing or billeting.
(U) 1. Heavy losses were incurred on 2 January at AP BAC, which is
west of Tan Hiep and southwest of Saigon. Five aircraft sustained heavy
damage and were repaired in the field. Two of the five were recovered by
other aircraft and the other three flown out under their own power.
(U) 2. Aircraft availability was not good during the early portion
of this period. Factors affecting availability were battle damages requiring
extensive repair, rotation to CONUS of large numbers of trained mechanics,
in several helicopter companies a continuing parts shortage for many items
on the CH-21 helicopter, preparation of UH-1A aircraft for return to CONUS,
acceptance of UH-B's in the UTT, 57th Medical Detachment and 45th UH-1
Section, low experience level of replacement mechanics, and flying hour
commitments far in excess of maintenance capabilities.
(U) 3. Six CH-21 aircraft were destroyed during January, February and
March. The 33d Transportation Company lost one CH-21 in a local accident
in April. No aircraft destroyed in May, but several suffered heavy damage
(U) 4. On 11 June a severe windstorm struck Tan Son Nhut airfield,
Saigon, severely damaging almost all of the 57th Transportation Company's
CH-21's and O-lD's, as well as O-1D assigned to HHD, 45th Trans Bn, Seven
replacement CH-21's were subsequently issued to the 57th.
(U) 5. A team of pilots and maintenance personnel from Boeing-Vertol
arrived in March 1963 to assist in improving performance characteristics
of the CH-21 helicopter. During the six week stay of the team, all helicopter
companies of this Battalion were visited and the most deficient helicopter
companies flown and inspected. In most cases repairs or modifications were
made on the spot and improvements noted. In most cases a lifting capability
improvement of the least 650 lbs was realized after repair of the helicopter.
Results obtained were mainly in increased manifold pressure which increased
lifting capability of the aircraft concerned. Some thirty one aircraft
were flown and inspected and results of the teams visit were satisfactory.
Training was given to selected mechanics and aviators working in maintenance
and as instructor pilots. This team departed Vietnam in April 1963. A report
entitled "Results of H-21 Performance improvement Program in the Republic
of Vietnam" is inclosed with supporting documents.
(U) 6. Overall aircraft availability and flying time improved with
the arrival of UH-1B aircraft as replacements. The 114th Air Mobile Company
became operational in May and increased the Battalion operational capabilities
with its relatively new aircraft and trained personnel. The UH-1B equipped
company could double the flying hours capability of the CH-21 equipped
Transportation Company (Lt Hel).
