ABSTRACT:
A continuous elongated trench is provided around a prison or military fortification. Parallel plates are provided on opposite side walls. Anti-personnel wires such as razor or barbed wire in concertina form are placed in the bottom or the trench. A light grid with large openings and weakened portions is placed over the trench and is supported on the plates. Anti-personnel explosives in the bottom of the trench and suspended within the trench beneath the grid deter crossing of the trench by persons, vehicles or objects. A covering over the grid blends the trench into the surrounding area.
