I reenlisted to a unit that I am not qualified for and it was accepted. The unit is looking at having me kicked out. What can I do?

Ask your unit who your Army Career Counselor is, even if they say there is not one on base you are supported by one somewhere. Make sure your situation is being explained by the them as well and not just by your unit.

Kicked out of the Army or the unit?

SPC (Join to see), you did not reenlist for a unit (Soldiers cannot reenlist for specific units), but for an area (Pacific long-tour, if you're in Japan) and the unit cannot kick you out for this or have you pay your bonus back.

See your Career Counselor IMMEDIATELY (not JAG/IG) for resolution. They will be able to work directly with HRC's Retention and Reclassification Branch.
