The M48 was one of the few vehicles in Vietnam whose armor afforded its crew members reasonable protection from their principal enemy: land mines. Therefore American M48s with front-mounted mine rollers, like the one at right in 1966, made daily runs along the oft-mined, two-lane Highway 19 between An Khe and Pleiku. This was much faster than using handheld minesweepers, preventing traffic pileups and reducing the opportunities for enemy ambushes. (History/Granger, NYC)
