About Us
The 4th Marine Raider Battalion Realism Unit, aka 4th MRB, is a realism unit in the Arma 3 community. We simulate a fictional unit within the Marine Special Operations Command (MARSOC) of the United States Marine Corps (USMC) and United States Special Operations Command (USSOCOM). The 4th MRB is structured and organized identical to a real life MARSOC battalion, with attached supporting USSOCOM units. The 4th MRB was founded by long-serving members of a different Arma 3 realism unit which emulates another real life United States Marine Corps Unit. The 4th MRB attempts to maintain the discipline, professionalism, and esprit de corps of real US Marine special operators. The fun and excitement members of this unit enjoy is the result of the difficult and challenging operations we are asked to perform and in developing skills and unique tactics commonly practiced by special operators within the special operations community.
