At the very end of the Vietnam War on the 30 April 1975, an NVA T-54 tank smashed through the opulent main gate of the RVN Presidential Palace in their capital city of Saigon, accompanied by onrushing North Vietnamese troops, at the conclusion of North Vietnam's conquering of the Southern. This widely seen image has come to be regarded by many as perhaps the defining moment of the end of the bloody 20-year-long conflict in Vietnam, as well as the fall of Republic of Vietnam and the imminent end of American participation in anti-communist activities in that region of Southeast Asia. According to the Pentagon, during the 1975 Spring Offensive, the ARVN forces lost 250 M48A3 tanks, 300 M41 tanks, 1,381 M113 APCs, 1,607 guns, 200 RCL guns and 63,000 M72 LAWs.
