I EASed out of the Marine Corps 20170317. I am seriously considering joining the Army now. Any tips?

Pro tip: go Airborne, whatever MOS you pick (as long as it's not something that doesn't have airborne like tankers).

So supply side, 92 series, has good senior promotions and you can be assigned to any base.

Edit: as mentioned, go airborne while you can get it in your contract if that's your thing.

Don't limit yourself, talk with prior-service recruiters for all Armed Services. Consider what MOS/AFSC you want to serve in and the opportunities they are offering. Pick the offer that most closely matches you personal life goals.
