Each unit only has a set amount of weapons and artillery. If a malfunction happens, there isn’t time to send that weapon to the manufacturer. It needs to be fixed immediately. That is the job of the Army 91F. He/she is the person who maintains and repairs these weapons to ensure each soldier has the ability to perform their duties.
In today’s post, I am going to give you an overview of the military occupational specialty 91F, small arms repairer. I will give you their basic job description, duties and responsibilities, the requirements to get this Army job and the training needed.
Army 91F Basic Job Description
The Army 91F, small arms – artillery repairer performs general maintenance and basic repairs on small arms, towed artillery and other infantry weapons.
Army 91F Responsibilities And Duties
As for responsibilities and duties:
- Performs direct and general support maintenance on small arms, other infantry weapons and towed artillery.
- Diagnoses and troubleshoots malfunctions of small arms and other infantry weapons and towed artillery.
- Supervises lower grade soldiers and provides technical guidance to the soldiers in the accomplishment of their duties.
And naturally, you are a soldier first, so you could be asked to do any number of other duties and play a roll in combat situations.
Requirements To Become an Army 91F
The requirements to become a 91F are:
- PULHES of 222221
- Physical demands rating is very heavy
- ASVAB score of 93 in General Maintenance (GM) or 88 in GM and 83 in General Technical (GT).
- U.S. citizenship not required
- No security clearance requirements
- Normal color vision
So the requirements are not too difficult.
Training For The Army 91F
As with all Army MOS’, you will first have to successfully complete Basic Combat Training where you will learn how to act and react in the heat of battle. From there, you travel to Aberdeen Proving Ground in Maryland for Advanced Individual Training (AIT) where you will learn:
- Electronic and mechanical principles and concepts,
- understanding schematics, drawings, blueprints and wiring diagrams,
- operating electronic, electrical and mechanical test equipment
- testing and maintenance of specific types of weapons systems.
Final Thoughts
While many soldiers have went for this MOS, it is needed as weapons must be regularly maintained and in some cases, repaired.
I see where most opinions say that soldiers should try hard to fast track to Warrant Officer status.
As for after Army, these skills can be helpful with arms manufacturers and even retail stores that sell small arms.
Or you could start your own business.
We would love to hear from any current or former small arms repairers, 91F. Please tell us more about this Army job.
