Grenades and antipersonnel devices
In addition to standard mines provided by their backers in China and the Soviet Union, Communist troops used a variety of antipersonnel devices, many handmade or obtained from US forces. Viet Cong soldiers dug up and reused American land mines, took Claymore mines from their tripods, and even cut open unexploded bombs to harvest components for their hand-made weapons. Many Viet Cong soldiers lost their lives in accidental explosions at low-tech bomb factories
