RIGGING ARMAMENT CARRIERS
FOR LOW-VELOCITY AIRDROP
SECTION I - RIGGING CARRIERS ON A 16-FOOT PLATFORM
DESCRIPTION OF LOAD
3-1. The unrigged M1025 armament carrier (Figure 3-1) is described in Chapter
1. The truck is rigged on a 16-foot type V platform for low-velocity airdrop. An
accompanying load weighing a minimum of 800 pounds and a maximum of
2,000 pounds must be rigged in the truck. The load requires two G-11 cargo
parachutes.
The following trucks can be rigged using the procedures given in this chapter:
M1025A1, M1025A2, and M1025A2 modified
M1026, M1026 (modified) and M1026A1
M966 and M966A1
M1036
M1043, M1043A1, and M1043A2
M1044 and M1044A1

M1046 and M1046A1
M1121
PREPARING PLATFORM
3-2. Prepare a 16-foot, type V airdrop platform using four tandem
links and 18 load tie-down clevises as shown in Figure 2-2.
Notes:
1. The nose bumper may or may not be installed.
2. Measurements given in this chapter are from the front
edge of the platform, NOT from the front edge of the nose bumper.

SECTION II - RIGGING CARRIERS ON A 20-FOOT PLATFORM WITH
ADDITIONAL ACCOMPANYING AMMUNITION LOAD
DESCRIPTION OF LOAD
3-16. The unrigged M1025 armament carrier (Figure 3-1) is described in
Chapter 1. The truck and an accompanying load are rigged on a 20-foot type V
platform for low-velocity airdrop. A load weighing a minimum of 800 pounds and
a maximum of 2,000 pounds must be rigged in the truck. The load requires
three G-11 cargo parachutes. The armament carriers listed on page 3-1 can be
rigged using the procedures in this section.
PREPARING PLATFORM
3-17. Prepare a 20-foot, type V airdrop platform according to TM 10-1670-268-
20&P/TO 13C7-52-22. Install four tandem links, two suspension links and 32
load tie-down clevises as shown in Figure 3-8.
Notes:
1. The nose bumper may or may not be installed.
2. Measurements given in this chapter are from the front edge of the
platform, NOT from the front edge of the nose bumper.
