The cratering charge is used to blow craters and to dig ditches. The container is olive-drab with yellow markings.
M2- and M3-series shaped charges, shown in Figure 2-6, are used to bore holes in earth, metal, masonry,
concrete, and road surfaces. They differ mainly in size. The M2-series charges weigh 15 pounds, and the M3-
series charges weigh 40 pounds. M2-series charges are packed in a moisture-resisting, molded-fiber container,
and use a fiber base to accomplish standoff. M3-series charges use a metal container and a metal tripod to effect
standoff. Both types of charge are olive-drab with yellow markings. The DODIC for the M2 series is M420. The
DODIC for the M3 series is M421.
