What is Burmese tiger pit?

A Burmese Tiger Pit is a pitfall trap that was created in the south pacific as a guerrilla warfair tactic. What it is is a pit, anywhere from four to ten feet deep, that is filled with about two dozen sharpened bamboo shafts all directed upwards. What happens is that once you finish the pit, you have to cover it with leaves and other things to hide it. While once useful for catching tigers, hence it's name, it was later realized that it could be used against enemies while fighting in the jungle. They take a foul step on top of the pit and fall in, incapacitating and/or killing them effectively.
