What is it like being a Social Worker in the Army? What are the MSW program and the job in the Army? How far can I expect to get, rank-wise?

You’ll most likely come in as an O-3. Depending on how many years you’ve been a social worker you might get some credit for that. There are decent loan repayment incentives and bonuses for social workers in the reserves. I am friends with 2 of them and they seem to like it. Talk to an amedd recruiter for more info

This is a very slim field for the Army. One you have to be an officer, promotions are generally at the at zone rate. Keep in mind that small fields for Officers often cut at O4. While being a major is respectable, it can be frustrating flatlining early in ones career. Again, very small forked. The military counts on civilian providers and chaplains to overcome many of the associated functions.

Here are the requirements on the Army official page: https://www.goarmy.com/careers-and-jobs/career-match/science-medicine/physical-mental-health/73a-social-worker.html

This looks like it's not offered to enlisted (it has an "x" next to enlisted but check mark next to officer, active duty, Guard and Reserve). It appears you'll have to become an officer to do it.

I honestly had no clue that the military had social worker as a job for Active, Guard or Reserve. I have never met any social workers that are in uniform.
