LX-4
MerrSonn's self-detonating perimeter mine, these proton weapons were buried a half-meter below the surface. Thermal gravity-sensitive sensors tell the weapon when a large vehicle or person is near, and triggers the detonator. The LX-4 is a refitted proton torpedo warhead, and make up for the LX-2's failings by being impossible to disarm. This causes problems for the Empire as well, since they cannot be stored easily.
