AIT is the school your soldier attends to learn his specific job in the Army. This job is also referred to as his MOS (Military Occupational Specialty). His AIT can last a few weeks or for the better part of a year depending on what his job is. He also may have to go to a different base than where he was for BCT (basic training).

AIT includes classroom instruction as well as hands-on training. Of course, depending on his specialty, the intensity of the training varies. If his MOS is infantry, he will be undergoing a training schedule very similar to that in BCT. If however, he has chosen a human relations specialty or mechanical specialty, he could be spending more of his time in a classroom type setting.

MOS 11B (11 Bravo – Infantry)

Infantry soldiers go through OSUT (One Station Unit Training). This means that they are at Ft Benning for both BCT and AIT. There is no real distinction between the two and there is only one graduation ceremony at the end of all of the training. The AIT phase of OSUT is five weeks long and includes spending several days (and overnight) in the field. 11B is considered a combat MOS and is closed to women.

From the Army website:

The infantry is the main land combat force and backbone of the Army. It’s equally important in peacetime and in combat. The Infantryman’s role is to be ready to defend our country in peacetime and to capture, destroy and repel enemy ground forces during combat.

The following are some duties expected of Infantrymen:

• Perform as a member of a fire team during drills and live combat
• Perform hand-to-hand combat
• Aid in the mobilization of vehicles, troops and weaponry
• Assist in reconnaissance missions
• Operate two-way radios and signal equipment
• Process prisoners of war and captured documents
• Learn to use, maintain and store various combat weaponry (rifles, machine guns, anti-tank mines, etc.)
