PROM-1

     Notes: This bounding APERS mine is a progressive development of the World War 2 Nazi S-mine, and except for more modern manufacture and explosive, the PROM-1 is similar to the S-mine. The PROM-1, like most bounding APERS mines, is triggered by pressure on one or more of exposed prongs at the top of the mine.  The user buries the mine almost completely except for the prongs, then removes the safety clip. Like many bounding APERS mines, the PROM-1 does have an option for use with a tripwire. Treading on one of the prongs causes a large grenade to jump into the air to a height of about a meter, then it detonates, spraying fragments in all directions in a wide area. Due to the height at which it detonates, twice the normal number of fragments will hit the abdomen and legs of victims. The PROM-1 contains a large amount of steel and is easily detected by mine detectors, but the plastic of the prongs is generally green in color and they are not easy to spot in undergrowth. The PROM-1 can be difficult to defuse, particularly if the mine has been in place for months, because the fuze becomes unstable over time and the PROM-1 can detonate at the slightest touch or even without being triggered.  Normal disposal of the PROM-1 is to blow it in place.  The PROM-1 kit includes three 6.1-meter tripwires. Tripwires operate on 3 kilograms of pressure, while the prongs require 9 kilograms of pressure to trigger.
