I recently signed papers puttingm e in the BEAR program, about 4 months ago. Since then I have changed my mind. My spouse has a good job opportunity at my current location as well as my unit has went throught leadership overhaul and is now a place where I want to stay. Is there any way to get out of the BEAR program once signed in to it?

You'll need get with your Career Counselor, but here is the regulation:

AR 601-280, Army Retention Program, Chapter 6:

6–11. Release and Removal from the BEAR Program.
a. Soldiers may request release from the program for hardship or compassionate reasons only. Fully documented cases will be submitted through the Soldier’s immediate commander and appropriate retention office to CG, HRC, Attn: AHRC-EPF-R-R, 2461 Eisenhower Avenue, ALEX VA 22331-0450, for consideration.
b. Soldiers released from the program will not be considered for reentry into the program, unless documentation is furnished to indicate the reasons for removal no longer exist.
c. Soldiers who fail to complete the training will be removed from the program, unless the training unit commander recommends that they be retained and rescheduled for a subsequent class date.
d. Soldiers who have been approved for entry into the BEAR Program and subsequently become disqualified or receive punishment under UCMJ will be reported to CG, HRC, Attn: AHRC-EPF-R-R, 2461 Eisenhower Avenue, 2461 Eisenhower Avenue, ALEX VA 22331-0450, DSN: 221-8020, for confirmation of assignment information prior to proceeding to the training site. Soldiers allowed to remain in the BEAR Program (upon waiver of disqualification) will be allowed to reenlist upon completion of training and receive all benefits from the program.
e. When release or removal from the program is necessary, the Soldier will be—
(1) Required to complete the period of service for which he or she extended under the program.
(2) Reclassified, if appropriate, and reassigned according to the needs of the Army.

AR is correct with the regulation but his first sentence is the key. Go see your Career Counselor. They can send a hotline requesting deletion if you have a reasonable explanation of why you want to drop the BEAR. Be aware though that if they approve the deletion that you will still have to honor the amount of months that you extended and that you will be IAW the needs of the Army.

Thanks for co-signing, crustyold79S!
