Military Occupational Specialty.

Allied Trades Specialist.

The Army accomplishes its mission with a variety of vehicles and equipment and when they need a part made or repaired immediately, and there is no other way to get it, they go to the Allied Trades Specialist.

These soldiers fabricate, repair and modify the metallic and non-metallic parts necessary for the Army to keep their equipment operating reliably.

After successfully completing 10 weeks of Army Basic Combat Training, you will attend Advanced Individual Training at Fort Lee, Virginia.

Where, the Army will train you to select the materials, tools and equipment to do the job, and train you to use various fabrication machines to shape metal parts to exact requirements.

You’ll train to operate tools like drill presses, tap and die sets, grinders and other power tools used in the creation of fabricated parts.

You’ll also train to weld using oxy-acetylene, metal inert gas and tungsten inert gas. In addition, you will learn how to use arc and air arc cutting and gouging equipment.
