CHAPTER 5

RIGGING SPECIFIC ACCOMPANYING LOADS

IN HMMWV-SERIES TRUCKS

DESCRIPTION OF LOADS

5-1. This chapter tells and shows how to rig specific items of Army equipment in

the cargo bodies of HMMWV-series trucks. All trucks on 16-foot and 20-foot

platforms must be rigged with a load in the truck. See the chapter or section for

the particular truck for the minimum and maximum allowable load weights. If

a specific piece of equipment is lighter than the minimum specified weight,

additional items must be rigged to meet the minimum weight requirement.

Since loads in actual tactical situations vary greatly, and equipment

changes rapidly, use these procedures as guides for rigging similar items.

 The loads shown in this chapter can be rigged in trucks of similar configuration and load capacity, unless the procedures specify that the load can be

rigged in only one model of truck. Consult the chapter or section for the truck

shown to find alternative truck models that can be used to rig the load.

CAUTION

Only ammunition listed in FM 10-500-53/MCRP 4-3.81/TO 13C7-18-41

may be airdropped. Package, mark, andlabel hazardous material

according to AFJMAN 24-204/TM 38-250.
