The Army special forces engineer sergeants are specialists across a wide range of disciplines. These disciplines include demolitions, constructions of field fortifications, and topographic survey techniques.

Duties performed by soldiers in MOS-18C include:

  • Perform and teach tasks in demolitions, explosives, field fortification, bridging, rigging, reconnaissance, and civil action projects
  • Interpret maps, overlays, photos, and charts
  • Carry out demolition raids against enemy military targets, such as bridges, railroads and fuel depots
  • Employ warfare tactics and techniques in infantry operations

Physical Requirements for MOS-18C

Special forces engineer sergeants have very demanding physical requirements. Good eyesight, night vision, and physical conditioning are required to reach mission objectives via parachute, land, or water. Also required is excellent hand-eye coordination to detonate or deactivate explosives.

In most instances, special forces engineer sergeants are required to be qualified divers, parachutists, and endurance runners.

Strength Requirement: No Standard Set.

Physical Profile Requirement: Army PULHES code 111221. This coding includes requirements in physical stamina and ability of the upper and lower extremities, hearing, eyesight, and psychiatric well-being. Codes of one and two mean that the soldier can deploy.

How to Become an SF Engineer Sergeant

You cannot enlist with a guarantee for this MOS. 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. Their Special Forces MOS is determined during the Special Forces Assessment and Selection portion of their training. This MOS determination is based on their interests, qualifications, and the "needs of the Army." Examples of enlisted MOSs include:

  • 18B - Special Operations Weapons Sergeant
  • 18C - Special Operations Engineer
  • 18D - Special Operations Medical Sergeant
  • 18E - Special Operations Communications Sergeant

Training Information

Due to the wide variety of missions, special forces engineer sergeants are trained swimmers, paratroopers, and survival experts, as well as trained in many forms of combat. Training for the MOS-18C consists of 44 weeks of formal classroom training and practice exercises.

Some of the skills you'll learn include:

  • Physical conditioning, parachuting, swimming, and scuba diving
  • Using land warfare weapons and communications devices
  • Handling and using explosives
  • Bomb and mine disposal

The Special Forces training pipeline is inarguably the toughest training program in the Army. It has a very high wash-out rate. Soldiers who are retraining into Special Forces, and who fail any of the training courses, can revert to their primary MOS (job). 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.
