There is no proper translation for this unit's designation. In German it is called Objektschutzregiment which would literally translate as "force protection regiment" but there's more than that to their tasks. For example, the regiment is also able to maintain airports in combat zones.
The regiment consists of four battalions, the first of which has three infantry squadrons and a air defense squadron, the second one has three infantry squadrons and a military intelligence squadron whereas the third specializes on explosive ordnance disposal, firefighting and airport clearance as well as maintenance. The fourth battalion is a reserve infantry battalion.
