Abstract: An RPG defeat system and method wherein a foam body is placed at a proximate a target. The foam body has a sufficiently low density to be pierceable by an RPG sensor without the RPG sensor being strained sufficiently to create a voltage. The foam body has a compressive strength sufficient to deform the RPG short circuiting a voltage pathway from the sensor to the RPG detonator. The foam body has a sufficient thickness and/or is spaced from the target to deform the RPG short circuiting the voltage pathway from the sensor to the RPG detonator before the sensor strikes the target and is strained creating a voltage.

Abstract: A method of treating a net (2) formed from interconnecting strands (4a, 4b) of ultra-high-molecular-weight polyethylene (UHMWPE), the net (2) being formed with knotless intersections (6), comprising the steps of: a) heating the net (2) to a temperature of from 80° to 135° C.; b) applying tension to the net (2); c) reducing the temperature to below 80° C.; and d) removing tension from the net (2).
