Cu Chi Tunnels

Many of the Viet Cong ( Communist) gorilla fighters lived underground an hour and a half from Saigon.
Tunnels were created to escape from the U.S. troops or to capture them.
Excellent camouflage techniques were used to hide the entrances of the tunnels. One also needed to be very slight to enter.
Many different types of entrances are positioned throughout the forest area.
This trap was used to kill the American soldier which traditionally captured tigers.
