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.
