Booby trap - white Baseball T-Shirt

A booby trap is a device or setup that is intended to kill, harm or surprise a person. It is usually triggered by the actions of the victim who did not know the booby trap was there. During the Vietnam War nearly 70% of American casualties were due to booby traps. In war, booby traps are a form of psychological warfare. They are designed to make soldiers slow down and be very cautious. As the word trap implies, they sometimes have some form of bait to attract the victim. At other times, the trap is set to act upon trespassers that come into personal or restricted areas. The device can be triggered when the victim performs some type of everyday action. For example opening a door, picking something up or switching something on.
