In order to facilitate defense in locations where stationary defense structures would be unwieldy or inefficient, the Brotherhood of Nod developed a series of emplacements that would provide heavy firepower in a small, compact package. The design itself is quite simple and easy to manufacture: a canopy with integrated targeting systems mounted on a flexible axis allowing it to rotate 360 degrees and a 75mm APDS cannon mounted onto the right side of the chassis which can move in over 90 degrees of the vertical firing arc, thus allowing the emplacement gunner to fire in almost every direction.
