SECTION III-RIGGING 20-MILLIMETER (MM) AMMUNITION
DESCRIPTION OF LOAD
5-33. Two hundred forty boxes of 20-mm ammunition are rigged for low-velocity airdrop on a 16-foot,
type V airdrop platform. All 20-mm ammunition packaged as shown and listed in FM 4-20.153/MCRP 4-
11.3B/TO 13C7-18-41, as certified for low-velocity airdrop, may be rigged using these procedures. This
load uses five G-11 cargo parachutes. Each load must weigh at least 5,040 pounds, including parachutes.
