Abstract:

Project Armor Obstacle was a series of cratering and obstacle effectiveness experiments conducted in October and November 1972 at Fort Peck, Montana. The cratering tests consisted of several deliberate road cratering designs and a series of equal weight cratering comparisons. Explosives involved were TNT, nitromethane, a 10 aluminized slurry, ANFO, the Armys 40-lb cratering charge, and the Experimental XM-180 cratering charge. Various wheeled and tracked vehicles attempted to negotiate the road craters that were produced. Obstacle effectiveness tests were also conducted in a crater produced by 17 tons of nitromethane at 6 meters depth of burial with an open access hole. Test results demonstrated the validity of the various road crater designs and their effectiveness as obstacles.
