The special operations weapons sergeant employs conventional and unconventional warfare tactics and techniques in individual and small unit infantry operations. This position trains and maintains proficiency in all Major Duties, and employs highly demanding conventional and high-risk unconventional warfare tactics and techniques in the employment of individual domestic, foreign small arms, light and heavy crew-served weapons, anti-aircraft and anti-armor weapons.

They also supervise and perform construction of hasty fortifications and control execution of tactical conventional and unconventional operational employment and functioning of all types of U.S. light weapons (up to and including 50 cal MG), U.S. heavy weapons (up to and including the 4.2in and 120mm mortar and 106mm RR), man-portable air defense weapons and U.S. antiarmor weapons (including anti-tank missile systems), to perform tactical operations.

They must maintain proficiency with the employment and functions of all foreign high-density light and heavy weapons, man-portable air defense, and anti-armor weapons. Additionally, they evaluate terrain, select weapons emplacements, site, and assign targets and areas of fire. Finally, the special operations weapons sergeant reads, interprets, and prepares combat orders.

You cannot enlist with a guarantee for this MOS. New recruits interested in Special Forces may enlist under the 18X, Special Forces Enlistment Option. They then attend Infantry OSUT (basic training and infantry training in one course), and their Special Forces MOS (18B - Special Operations Weapons Sergeant, 18C - Special Operations Engineer, 18D - Special Operations Medical Sergeant, or 18E - Special Operations Communications Sergeant) is determined during the Special Forces Assessment and Selection portion of their training, based on their interests, qualifications, and the "needs of the Army."

Training Information

  • Four weeks at the Special Operations Preparation Course (SOPC) at McKenna MOUT Site, Fort Benning, GA.

The Special Forces training pipeline is inarguably the toughest training program in the Army and has a very high wash-out rate. Soldiers who are retraining into Special Forces, who fail any of the above training courses, revert to their primary MOS (job). New recruits, who enlist under the 18X Special Forces Enlistment Program, who fail to complete any of the above training courses, are reassigned as 11B, Infantryman.
