Enlistment date: XX March 2009
TPU requirement fulfilled: XX March 2015 (6 years)
ETS: XX March 2017
The local career counselor has informed me that I have two options: request transfer into the IRR, which may take many months of paperwork, or complete a reenlistment contract that reassigns me into the IRR effective XX March 2015, so it'd be guaranteed to be a lot quicker. Is there any reason I would prefer one option over the other, and would either one have any significant effect on my entitlements such as Montgomery GI Bill?
