Ben Het Battle
Only tank battle during Viet-nam war

On 3 March 1969, Ben Het was attacked by the PAVN 66th Regiment, supported by armored vehicles of the 4th Battalion, 202nd Armored Regiment. One of the attacking PT-76s detonated a land mine, which alerted the camp and lit up the other PT-76s attacking the base. Flares were sent up, exposing the attacking tanks, but by sighting in on muzzle flashes, one PT-76 scored a direct hit on the turret of an M-48 of the 1st Battalion, 69th Armor Regiment, killing two crewmen and wounding the other two. Another M-48, using the same technique, destroyed a PT-76 with their second shot. At daybreak, the battlefield revealed the wreckage of two PT-76s and one BTR-50 armored personnel carrier
