Shipping and storage data.
Placed munitions include demolition materials (and associated components) and land mines.
Demolition materials are used for the destruction of structures, facilities, or materials to accomplish a military
objective. The data sheets for demolition explosives and associated materials are contained in TM 43-0001-38.
Demolition materials require some form of initiating explosive or priming device in order to function.
Blasting Caps. Two standard blasting caps may be used. They are the M7 non-electric blasting cap and the M6
electric blasting cap. Both of these items are shown in Figure 2-1. Neither item will be marked or color coded.
Both are silver or chrome-colored. The DODIC for the M7 non-electric blasting cap is M131. The DODIC for the
M6 electric blasting cap is M130.
Bulk Demolition Charges. The four basic types of demolition explosives used are trinitrotoluene (TNT) block
charges, M112 blocks, M118 blocks (FLEX-X), and special-purpose charges.
TNT block charges come in three different sizes, as shown in Figure 2-2. The 1/4-pound (DODIC M030) charge
is round, and is used primarily for training. The 1/2-pound (DODIC M031) and 1-pound (DODIC M032) charges
are rectangular, and are used for general demolition work. All three charges have waterproof cardboard
containers, metal ends, and a threaded cap well in one end. All three are olive-drab with yellow markings.
M112 blocks (shown in Figure 2-3) are packaged in two configurations. One configuration consists of 30
individual blocks packed in a wire-bound box. The other is the M183 demolition charge assembly, which consists
of 16 M112 blocks. The M112 block is used primarily for cutting and breaching demolition work. An M112 block
consists of 1 1/4 pounds of composition C-4 packed in a Mylar-film container with pressure-sensitive tape on one
side. Its color code is olive-drab with yellow markings. The DODIC for the boxed M112 blocks is M023. The
DODIC for the M183 demolition charge assembly is M757.
M118 blocks (FLEX-X) also come packaged in two configurations, as shown in Figure 2-4. The first is the M118
demolition charge (DODIC M024), commonly referred to as sheet explosive. It is packaged in 1/2-inch sheets,
four sheets to a package, 20 packages to a box. The second configuration is the M186 roll demolition charge
(DODIC M060). M186 blocks come 50 per roll on a plastic spool, rather than in sheet form. Both configurations
are designed to be used as cutting charges, especially against steel targets. The color code for both is olive-drab
with yellow markings.
