SECTION III - RIGGING STRIKER IN ARMAMENT CARRIER-
CONFIGURED M1025 HMMWV-SERIES TRUCK
ON A 16-FOOT PLATFORM
DESCRIPTION OF LOAD
3-32. The unrigged M1025A2 armament carrier is described in Chapter 1. The
Striker vehicle is configured as a field artillery observer carrier. The Striker
serves fire direction control, self-location, target designation and night observa-
tion functions. The Striker components are contained within the truck. This
load requires three G-11 cargo parachutes. Striker-equipped trucks using the
M1025 and M1025A1 models are rigged using these procedures.
PREPARING PLATFORM
3-33. Prepare a 16-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 20
load tie-down clevises as shown in Figure 3-20.
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.

3.
Install a clevis on bushing 2 of each front tandem link.
4.
Install a clevis on bushing 4 of each rear tandem link.
5.
Starting at the front of the platform, install clevises on each platform side rail using the
bushings bolted on holes 5, 15, 20, 21,23, and 27.
6.
Install a clevis on bushing 17 in an inverted position. Install a clevis on bushing 17A in the
normal position. Bolt an additional clevis to each of the clevises on the 17th bushings.
7.
Starting at the front of the platform, number the clevises bolted to the right side of the
platform from 1 through 10, and those bolted to the left side from 1A through 10A. Number
the clevises installed on the 17th bushings 5 and 5A. Number the clevises bolted to these
clevises 4 and 4A.
8.
Label the tie-down rings according to FM 4-20.102/TO 13C7-1-5.

RIGGING EXPANDED CAPACITY HMMWV-SERIES TRUCKS
FOR LOW-VELOCITY AIRDROP
SECTION I - RIGGING M1113 TRUCK WITH M56 SMOKE GENERATOR
ON A 16-FOOT PLATFORM
DESCRIPTION OF LOAD
4-1. The M1113 HMMWV-series truck has a heavy-duty suspension and is
rigged the same as the M998 truck except as noted. The truck is rigged on a 16-
foot, type V airdrop platform for low-velocity airdrop. The M56 Smoke Generator
is shown as the accompanying load. The procedure for rigging the M56 smoke
generator in the truck is given in this chapter. An accompanying load weighing
a minimum of 800 pounds and a maximum of 2,500 pounds must be rigged in
the truck. The load requires three G-11 cargo parachutes.
PREPARING PLATFORM
4-2. Prepare a 16-foot, type V airdrop platform according to TM 10-1670-268-
20&P/TO 13C7-52-22. Install four tandem links and 18 load tie-down
clevises according to FM 4-20.102/TO 13C7-1-5, and as shown in Figure 4-1.
NOTES:
1. The nose bumper may or may not be installed.
2. Measurements given in the instructions for this load are from the front
edge of the platform, NOT from the front edge of the nose bumper.

3. Install a clevis on bushing 1 of each front tandem link.
4. Install a clevis on bushing 4 of each rear tandem link.
5. Starting at the front of the platform, install clevises on each platform side rail using the bushings
bolted on holes 5, 15, 20, 21 and 25.
6. Install a clevis on bushing 17 in an inverted position. Install a bushing on clevis 17A in the normal
position. Bolt an additional clevis to each of these clevises.
7. Starting at the front of the platform, number the clevises bolted to the right side of the platform
from 1 through 9, and those bolted to the left side from 1A through 9A. Number the clevises on the
17th bushings 5 and 5A. Number the clevises bolted to these clevises clevises 4 and 4A.
8. Label the tie-down rings according to FM 4-20.102/TO 13C7-1-5.
