Appendix F

Vehicle Movements and Convoys

Proper management of vehicle movements and convoy procedures will ultimately affect the number of vehicles on the battlefield and, more importantly, their timeliness in getting there. All leaders should ensure that the following conditions have been met during movement operations.



F-1. The M809/939 Series 5-ton cargo truck, used to tow the M1022A1 dolly set laden with the JTAGS shelter, must be loaded with at least 3 tons when towing the combination. Additionally, vehicle drivers must be made aware of the need for extra caution.

F-2. Drivers should be made aware that driving accidents involving the M939 series 5-ton trucks are commonly the result of vehicle operators driving too fast for conditions and/or locking the wheels when attempting to stop their vehicles.

F-3. The air brakes of the M939 series trucks are very sensitive when the trucks are lightly loaded, empty, or when operating the vehicle on wet or slippery pavement. The operator must gradually apply the brakes when stopping the vehicle. "Overbraking" will lock up the rear sets of wheels. Locked wheels may cause the engine to stall, which in turn leads to loss of steering. Any of these individual scenarios can lead to loss of vehicle control, resulting in collisions, jackknifing, and rollovers.

F-4. Maximum safe operating speeds are as follows:

Highway and Secondary Roads

40 miles per hour

Cross-Country Roads

35 miles per hour

Sand and Snow

25 miles per hour

Icy Conditions

12 miles per hour

F-5. Additionally, drivers should be advised to not use the hand throttle while driving. The hand throttle will not disengage when brakes are applied.

F-6. The JTAGS Product Office issued a memorandum subject: Request for Overload Waiver Approval for the M809/M939 Series 5 Ton Tactical Truck to Tow the M1022A1 Dolly Set Laden with an Army Rigid Wall Shelter, dated 5 February 1996, approving the use of the truck with the dolly set and shelter combination.

F-7. Unobstructed access is needed for organic transport vehicles to allow room for maneuvering shelter into position. Turning radius for the shelter is approximately 60 feet. Planners should verify that any routes used by JTAGS shelters meet turning radius requirements of the mobilizer.



F-8. This paragraph establishes procedures for the safe, effective road march of JTAGS personnel and equipment and provides guidelines for consistent, detailed convoy briefings. This applies to all personnel assigned, attached, or otherwise deployed with a JTAGS element.

F-9. The items below are designed to assist the convoy commander in ensuring that information relevant to the road march of personnel and equipment are addressed for the safest, most efficient move possible.
