Army MOS 11C also scout enemy forces and neutralize land mines.

Soldiers receive their training through boot camp (10 weeks) and OSUT training (12 weeks).

7. What’s the necessary ASVAB score for 11X?

Those that are interested in joining the infantry division of the U.S. Army need to take the Armed Services Vocational Aptitude Battery (ASVAB).

The ASVAB is a series of tests like what you would take in high school which helps determine what your strengths and weaknesses are in terms of knowledge.

For example, someone that is more mechanically inclined will perform way better on certain parts of the ASVAB compared to another individual that is more “right-brain” and might excel in other Military Occupational Specialties.

In order to qualify for MOS 11B or MOS 11C, you must score a minimum of Combat (CO): 87 on the ASVAB.

Speaking with a local recruiter provides you with more details about the ASAB, and how to perform well on the test.

8. What is ‘Option 40’?

Option 40 is an enlistment option that new recruits have the option of selecting.

It slots you into the 75th Ranger Regiment as an Army Infantryman (MOS 11B) or Indirect Fire Infantryman (MOS 11C).

The military track begins at One Station Unit Training (OSUT) after completing the initial boot camp.

OSUT training focuses on the different specialties between soldiers becoming MOS 11B compared to 11C.

Option 40 also gives recruits the option of attending Airborne School and The Ranger Assessment and Selection Program (RASP 1) if they seek to join an elite force.

Option 40 is an exciting option, yet many recruits do not make it through all the demanding training.

Failure to complete the training allows the Army to remove you from the track and assign you wherever the military branch has needs for service.

However, it is an exciting way to join the Airbourne School or become a Ranger if you have the right mindset and dedication.

9. What is OSUT?

Army One Station Unit Training, or OSUT, is a training program that combines boot camp (Basic Combat Training) with Advanced Individual Training (AIT).

For example, an MOS 11B soldier receives boot camp training along with AIT training in the same location.

Meanwhile, a more advanced Military Occupational Specialty (MOS) would require a soldier to go through boot camp before leaving a BCT training compound to focus on AIT training at another facility.

As a result, your Drill Sergeants also remain with you through both types of training.

Since soldiers do not need to relocate for OSUT, the purpose is to foster more camaraderie within the ranks.

One Station Unit Training is for six different Military Occupational Specialties within MOS 11X.

10. What determines which route you will go in the Army?

First, you need to qualify for a MOS 11X specialty like Indirect Fire Infantryman by scoring high enough on the ASVAB and meeting other basic requirements.

Then you need to survive One Station Unit Training to remain in the Army.

Your performance at OSUT will determine your job placement for your first permanent assignment.

Those that choose Option 40 have the freedom of considering specialty training programs like the Army Airborne School as well.

Therefore, you could end up serving the Army in a non-combat MOS, field MOS 11X specialty, or advanced specialty like Army Ranger depending on your performance.

11. How much do Infantrymen make in the Army?

The Army pays personnel according to their rank and time in service. A new recruit can currently expect a monthly base pay of about $1,900 after BCT and AIT.

12. Does the Army Infantry get a signing bonus?

As of June 2023, the Army is offering a signing bonus of up to $40K for infantryman jobs. This may require an extended contract time, but you’ll need to talk to a recruiter for the details.

13. What branch of the service offers the highest signing bonus?

Currently, the U.S. Army is offering a large number of signing bonuses for positions in the infantry, rocket launching systems, fire control specialists, and more.

14. What MOS should I enlist under to join Army Special Forces?

Army MOS 11X serves as a starting point for several elite Army organizations, including Airborne, Rangers, Sniper School, and Pathfinder School.
