How many military occupational skills and/or identifiers do you/did you have?

1 MOS (12A Engineer Officer) with six ASIs (2B, 3S, 5S, 5W, 6P, 6S, S4). The Army has 120 MOS (fluctuates over time) with I do not know how many ASIs. The key that people need to understand is that MOS and ASI are a means the Army can use to manage its human talent. When ASIs are written into MTOEs then the Army has a defined requirement. When ASIs are searchable within an HRC system then the Army has a way to know how many personnel have that skill. Smart ORSA and TRADOC people can then figure out how many courses and school slots are needed on an annual basis to meet the defined requirement. MOSs and ASIs are therefore a strategic personnel management tool.

SGM (Join to see) I had a few. The infantry was tag along from my service as a Marine. It seems I couldn't figure out what I wanted to do when I grew up.

Mine were:

11B (Infantry), 71L (Administrative Clerk), 42A (Human Resources), 91X (Maintenance Supervisor), and 31D (CID Special Agent)

ASIs 4P (Information Operations) and 6Q (Additional Duty Safety Officer)
SQIs 4 (Recruiter) and 8 (Instructor)

I currently only have the one in MI, but I will be going to school soon to pick up Signal. I have done stints in nearly every operational capacity and have an additional duty in Safety currently.

I would eventually like to start learning the sustainment side of the house.

What is unusual is that I with 18 years in the Guard have only ONE MOS.

I have one ASI and one PDSI
1F, H1B

Just one MOS (11B) but as of right now four ASIs: F7 (Pathfinder), 1P (Parachutist), 2B (Air Assault), and 2C (Javelin Gunner). One SQI: 8 (Instructor), and one PDSI: B1A (Basic Instructor). Working on another ASI now

I started off as an 88M (truck driver) in the Minnesota National Guard, then changed to 63B (mechanic) in the Guard. Joined the Regular Army as a 63B. Went into the Army Reserve as a 63B, then became a 915A (Maintenance Warrant officer). This MOS changes to 915E at CW3. After about 8 years as a WO, I changed over 251A (Information Technology Warrant Officer). This MOS was merged with 254A and is now a 255A Information Systems Technician. So, technically, I've had 6 MOS'. :)

Military Police, Infantry, EOD, Combat Engineer, NBC and I was informed that because i was a member of a CST (WMD) team, we were given our own MOS (not too sure about that one)
I also have Technical Escort, Recruiter and Instructor Identifier.

Semper gumbie is the actual expression. Especially if you were a infantryman. I went from 3 tours in 4 years of active service to status to being mobilized as a 0193 staffing/sourcing/admin/training chief for the entire marine forces reserve. When you have no funding your personnel must learn 4 or 5 jobs to stay self supporting.

Just my MOS of 91M that was originally 63T before all maintenance MOSs merged in 2008 to 91 series.

In adition to that I have the H8 (vehicle recovery) ASI, and I have the M (1SG), 2 (Training developer), and 8 (Instructor) SQIs. I also have the GM for my language identifier in German.

I currently have two MOS's. I am primarily a 13D, but I have a secondary 13B MOS. This made me a more valuable asset to my unit, as I can help in either of the sections in my unit. The Commander tries to get more people to do this, but many don't meet certain requirements, or they just don't want to leave home for training.
