Well, you had your chance ... haha
BEAR = ExtensionThe
BEAR Program is designed to entice Soldiers in balanced and overstrength MOSs to
extend their contracts for up to 48 months (2 years past new MOS AIT end date) and receive a bonus (upon reenlistment within 90 days of graduation date) once they graduate AIT and are awarded a Shortage MOS.
Since you are in an understrength MOS, you cannot apply, unless you're looking at EOD or a couple MI MOSs.
Option 3 = ReenlistmentOption 3, Army Training Option is offered to all initial term Soldiers. They will be given a list (normally about 5 or 10) of MOSs that the Army is offering through your Career Counselor. Once you are "qualified" for te MOS by the Career Counselor, you can reenlist for that MOS.
When you reenlist for Option 3, you do not qualify for a bonus (unless you are deployed and you're getting "deployment" bonus; not an MOS specific bonus) because you do not hold the MOS yet.
Hope this helps and if you have any additional questions, please call on this community.
