Exhibits in the war museum

In the large, overgrown field behind the Siem Reap War Museum, you will find a collection of heavy weapons and war machines, most of which were Soviet made, and came to Cambodia as gifts from Vietnam.
At the same time that China was supporting the Khmer Rouge, the US was giving weapons to Lon Nol’s republican army, who was fighting the communists. The US may or may not have known, but corrupt Lon Nol officials were reselling the weapons to the Khmer Rouge. So, American weapons were used on both sides of the war.
