The typical outwear of so called vietcongs include; hammock(to avoid the impact of bombs when sleeping), Ho Chi Minh-sandals, packet of rice, scarf(to be used in the battlefield in case of injury and against teargas; as a sign for another vietcongs to recognize; and protect identity in the meetings, so no spys would afterwards recognize you), waterbottle, AK-47 and a flashlight.
This large crater was created by a bomb from an American B52 bomber when they carpet-bombed the area in the late 1960's. They managed to destroy substantial sections of the tunnels.
As well as the tunnels, you can also fire various weapons such as an AK-47, M16, M60 or Magnum 44 where each bullet costs between 20-25,000 VND but for a minimum of 10 bullets.
This is a last american tank that was destroyed with delay mine in Cu Chi area.
I think that it was 1975.
In the pic there is a secret entrance to the tunnels. ALmost impossible to westerner to get in through these holes.
If you go down to a restored and extended Vietkongs' tunnel, I think the shortest tunnel is enough. There is very hot, humid and also tight.
