Here are the most frequently asked questions about Army MOS 11X:
What’s the difference between 11X and 11B?
Army MOS 11X is the overall term for the infantry job field.
It involves multiple Military Occupational Specialties including MOS 11B and MOS 11C.
Meanwhile, Army Infantryman (MOS 11B) is an actual military job title with a specific list of duties and responsibilities.
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.
What is ‘Option 40’?
Option 40 is an enlistment option that new recruits have the option of selecting.
It slots you to 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 specialities 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 you are seeking 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.

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, a MOS 11B soldier receives boot camp training along with AIT training.
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.
What determines which route you will go to in the Army?
First, you need to qualify for a MOS 11X speciality 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 job placement for your first permanent assignment.
Those that choose Option 40 have the freedom of considering speciality training programs like the Army Airbourne School as well.
Therefore, you could end up serving the Army in a non-combat MOS, field MOS 11X speciality, or advanced speciality like Army Ranger depending on your performance.
