Cambodia was consumed by civil war and insurgency for the last three decades of the twentieth century as Khmer Rouge, royalist, Vietnamese, Thai and American forces struggled for power in various coalitions and combinations. The vehicles, armaments and materiel collected here reflect the international nature of the combatants.
One of the best features of the place is some of the exhibits have signage telling when and where it was originally produced, who used it in Cambodia and when it was retired or captured.

The museum is on the road to the airport, and took me fifteen minutes to get to by tuk-tuk. It costs a few dollars and a guide is included in the fee if you wish. Plan to spend an hour or more once you're there. Despite its rustic setting, this is far superior in my opinion to the "War Reparations Museum" in Saigon (HCMC).
