The M48’s chassis was adapted to a variety of more specialized vehicles, all of which saw use in Vietnam. It could carry bulldozer blades and mine exploders. The M67 shot flames from its barrel. The M88 was an armored recovery vehicle capable of towing disabled M48s. And when an armored column encountered a river it could not ford, the M48A2 AVLB (armored vehicle-launched bridge) was called into action. Carrying a mechanically extended scissors-type bridge totaling 63 feet on its hull, the AVLB could span bodies of water up to 60 feet. (U.S. Army)
