1. Explosive a substance that goes through a chemical reaction
that produces sudden expansion/reaction of the ma-
terial, usually accompanied by the production of heat
and large violent change in pressure
2. Low Velocity Explo- changes from solid state to a gaseous state over a
sive sustained period up to 400 m/s
- ideal for pushing effect
3. High Velocity Explo- changes from gaseous state almost instantaneously
sive at 1000 m/s
- ideal for cutting and/or shattering effect
4. Relative Effective- the shattering effect of the explosive in relation to
ness Factor TNT
- less than 1.0 = good for pushing effect
- more than 1.0 = good for cutting/shattering effect
5. Explosives selected purpose
should fit the mission
particular relative power

6. Airfield Destruction creating craters on the surface to prevent planes from
landing/taking off for the enemy but can be seized by
the U.S. and fixed relatively easily for our use
7. Bridge Deconstruc- either partial or total destruction using all types of
tion explosives for the deck but leaves abutments in use
for U.S. forces to span if needed
8. Building Deconstruc- destroy structures to prevent the use by enemy

9. Equipment Decon- destruction of enemy tools
struction
10. Steel and Log Posts prevents the movement of troops through an area of
operation by creating an obstacle
11. Explosives in Block C4 (M112)
Form = TNT (1 lb & 1/2 lb)
12. Explosives in Cylin- M1 Dynamite
drical Form = TNT (1/4 lb)
H6 Cratering Charges
Shaped Charges (15 lb and 40 lb)
Bangalore Torpedo (M1A2 and M1A3)
13. Block Demolition prepackaged, high explosives (HE) charges for gen-
Charges eral demolition operations, such as cutting, breach-
ing, and cratering
14. Transmission Line transmits chockwave from the blasting cap to the
explosive charge
15. Line Main piece of det cord stretched in a line
16. Ring Main piece of det cord tied in a circle with a square knot
17. Priming Charge used to set off the explosive charge (examples = det
cord, MDI, and/or time delayed)
18. Branch Line det cord or MDI stretching from the line main or ring
main of the firing system to the explosive charge
19. Time Fuse transmits a time delayed split to a non-electric blast-
ing cap
20. Modernized Demoli- a project name given to a new family of non-electric
tion Initiators (MDI) blasting caps, non-electric boosters, and other asso-
ciated demo items
- improves reliability and safety
- ALL components are sealed and are NOT easily
