The S.O.B. (Special Operation Barrier) can best be described as a movable rifle grade ballistic wall. Each S.O.B. is a freestanding wall that offers considerable protection (CAL .50 AP, M2, 708 GR).
The S.O.B. was originally designed for embassy checkpoint fortification. However when fitted with the optional wheels and ballistic aprons they are idea for large facilities such as nuclear power plants, oil refiners, airports, etc. In dynamic situations they can be rolled to multiple positions.
The gun ports are sized to accommodate weapon, optics and light. Multiple gun ports support multiple operators and angles of defense.
