Information regarding MARSOC's capabilities in combat and it's structure.


About the (MARSOC) MILSIM Unit

Established in March 2015 MARSOC has grown to be one of the best military simuatlion units with-in the arma community, founded by A. Mitchell.


The Marine Special Operations Command realism unit is a unit in which enforces a realistic type approach to the game of ArmA 3 like many other realism units tho as we portray a special operations unit, we create more of an advanced, specialized point of training and conflict experience by teaching more in-depth skills and techniques, this then allows the serving men to fight with more mind set then the average online marine. We are looking to induct dedicated, mature members willing to put the time and effort into bettering their skills and strategies for the unit.


The skills you will be taught in the Marine Special Operations Command may also be used in the real world, as what we teach you is from real life experience and pre-taught knowledge, the current serving personnel within the Marine Special Operations Command realism unit range from soon to be military to active or ex-military personnel meaning what we teach you is coming from real experience.


Recruits will go through a series of courses and tests to make sure that they are ready to take on the challenges the Marine Special Operations Command will come across in combat. These courses will range from battle drills to learning and familiarization with various U.S. and foreign weapons.
