Michael Yon takes a closer look at bomb tricks and techniques in Afghanistan.
The snapper uses a tire for a diaphragm in which nails are used for contacts. When a vehicle rolls over a snapper, the circuit closes. To avoid CIVCAS, the enemy waits in hiding with a battery. One of the electrodes is connected. Traffic is allowed to roll over the snapper but there is no explosion. When the target approaches, the enemy attaches the other connection and now the snapper is ARMED.
