SECTION IV-RIGGING THE MACS PAC ON A 20-FOOT, TYPE V PLATFORM
DESCRIPTION OF LOAD
8-53. Ninety-six 155-mm projectiles, 79 power canisters and 15 fuse cans are rigged for low-velocity
airdrop on a 20-foot, type V platform. The load uses three G-11B cargo parachutes. Refer to FM 4-
20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 for the weight limitations and for
the number of parachutes to be used.
Notes.
1. The load shown is using metal crates. However, wooden crates may be used with three
lashings and a load binder.
2. If the metal locking rods are missing, three lashings, D-rings and load binders will be needed.
PREPARING PLATFORM
8-54. Prepare a 20-foot, type V platform as shown in Figure 8-42.
