Appendix C

Vehicle Preparation

Efficient equipment preparation for movement is a unit responsibility. Unit personnel reduce vehicles according to mode of transportation and the carrier's additional instruction. PSA/DACG personnel may reduce vehicles so they will fit into cargo areas whose particularly low overhead clearance may demand maximum reduction. This appendix contains procedures for reduction of unit vehicles.


C-1. Efficiently preparing cargo saves valuable cargo space aboard vessels and aircraft. Other advantages are greater integrity of unit equipment, less cargo handling, less chance for unit equipment to become delayed or lost, and significant cost savings.

C-2. Built-up vehicles will not be transported on vessels or commercial conveyances without MACOM approval. These types of vehicles typically have overhead clearance problems along rail lines and in vessel compartments. When built up vehicles are permitted, for example, a temporary substitute for a TOE authorized shelter, the new dimensions must be entered on the AUEL. When mounted on a vehicle, the built-up shelter height must not exceed the height of the authorized shelter. Authorized shelter heights are designed to accommodate both the vehicles vertical balance and overhead clearance on selected transportation modes.


C-3. Prepare unit cargo (vehicles and equipment) for shipment according to the mode of transportation and the type of move. If a unit moves organically, it moves vehicles in an operationally reduced configuration, such as mirrors mounted and windshields up. Reduce loads according to TB 55-46-1 and the movement order. Further reduction specified by the movement order occurs in the POE staging area. RC units that convoy to a MS before deployment will maximize use of their organic cargo capacity by reducing loads for the deployment at the MS. Depending on the strategic lift asset for deployment, full reduction may or may not be required.

C-4. Make every effort to support the commander's concept of operations. When preparing vehicles for shipment, unit personnel must be sure that equipment conforms to clearance and space restrictions. Personnel must do the following:

  • Reduce vehicle length and width by folding in side-mounted mirrors and removing storage baskets that overhang the vehicle's fixed dimensions.
  • Remove antennas.
  • Keep windshields and cab canvas in the up position.
  • Leave exhaust stacks in place.
  • Reduce height as needed for rail clearance. Check with the ITO.
  • Reduce the length, width, and height of the vehicle only when specified in the movement order.


C-5. Take the following steps to prepare the vehicle:

  • Thoroughly clean the vehicle.
  • Ensure the vehicle is mechanically sound, free of leaks, drips, and other operational defects.
  • Fill fuel tanks only to three-quarters of their capacity. Any additional fuel increases the chance for spillage. Do not put hazardous labels or placards on vehicles for fuel in the tanks.
  • Do not fill trailer mounted equipment containing combustion engines, such as generator sets, to more than one-half of their fuel capacity.
  • Ship 5-gallon fuel cans three-quarters full of diesel fuel if they are shipped in approved vehicle storage racks. Inspect fuel cans for serviceable lid gaskets, leaks, and other defects prohibiting their use as fuel containers.
  • Do not leave removable crew served weapons, such as spare barrels and other sensitive items, mounted or stored in the vehicle. Instead, consolidate them and place in a secure container. Seal the container and lock it with an appropriate locking device.
  • Equip all vehicles with serviceable and proper lifting/tie-down devices or shackles. Remove T hooks from combat vehicles and replace them with screw pin shackles.
  • Secure ignition keys to the steering wheel with wire. The wire must be long enough to reach the ignition. Give copies of container keys to the unit liaison team or supercargoes accompanying the cargo.
  • Do not cover headlights, windshields, or mirrors with tape.
  • Ensure fire extinguishers are in the approved mounting bracket if they are kept with vehicles during shipment.
  • Keep driver compartments and steering wheels unlocked.
  • To preclude moisture damage to radios, store them in secured containers. If radios are shipped mounted in the vehicles, secure them with a padlock and chain; then cover them with plastic. Treat COMSEC equipment as classified cargo (see Appendix F).

If required for height reduction, lower canvas cab tops . Remove and box the frames for the cab canvas. Stow them only in the front cab of their respective vehicles. Keep the canvas threaded through the top windshield channel. Fold down the windshield with the canvas wrapped over the windshield and secure with manila rope. The method and degree of protection are left to the unit commander's discretion.

C-6. If removing exhaust stack extensions, protect the opening from weather and debris when the vehicle is not in operation. Use a tin can large enough to fit over the bottom exhaust stack pipe. Attach a wire to the can and exhaust stack bracket so the can may be removed and not lost when the vehicle is in operation. Place a shoe tag on the ignition switch or steering wheel to remind the operator to remove and install the can as appropriate..

C-7. When nesting equipment or placing cargo into unit vehicles, adhere to the following guidelines:

  • Maximize use of all vehicles cargo capacity, particularly cargo vehicles and trailers. If a trailer is nested in the back of a cargo truck, load cargo under and around the trailer.
  • Do not exceed the payload capacity.
  • Securely restrain the equipment and cargo in the vehicle body or chassis.
  • Ensure there is no metal-to-metal contact of loaded cargo. For example, a container loaded in the bed of a 5-ton cargo truck must have plywood between its bottom and the metal cargo bed.
  • After loading cargo into the cargo bed, cover it with canvas. Secure the canvas by lashing with manila rope. If steel strapping must be used, use enough padding to prevent damage to the canvas.
  • Update the AUEL if cargo loaded in a vehicle increases the dimensions or adds vehicle weight.
  • Box OVE and remove parts when practical. Store them aboard the vehicle for easy access at the POD. The OVE can be secured best in the vehicle OVE box. Lock or band the box itself. Store OVE and parts in the vehicle cab or under seat compartments (as long as seats can be secured). Or place OVE and parts into boxes or small crates and place the crates in the cargo bed. Mark boxes or crates with the vehicle's UIC and SUN.
  • Stow acetylene and oxygen tanks on a separate wooden pallet. Label tanks according to CFR 49 and clearly mark with the prime mover UIC/SUN.
