Forget the United States’ low-collateral damage Small Diameter Bomb, France has begun using concrete filled training bombs to literally crush Gadhafi’s tanks without causing massive explosions that can harm nearby civilians.
Apparently, the 660-pound “training bombs” have not been pressed into combat due to a lack of explosive munitions.
