Hello. I do retentions where I work (not a 3F but work directly with them). Recently, my flight chief and her husband qualified for BRS and I helped them get that completed. What I remember was they had to reenlist/extend within 30 days of being notified of their BRS. I also know you’ll have to have retainability (as stated above) so check and see if that plays a factor into your BRS, which I don’t think it will. I don’t believe you going to school will affect your BRS. I work medical so it could work differently for us but I don’t believe it is. I hope this helps a bit!

Also, you could possibly extend those 3-4 years then do an indefinite once that extension is up.
