To invoke the 6% rate the servicemember (or representative) must provide a written notice and a copy of their orders. You could certainly do it now if you wanted. The orders however, provide a termination date. This is good for your tickler file.
From what I have heard on a Marine recruits pay, this gap would be correct. Extensions would be of assistance. Requesting the orders as you arrange this would resolve several issues.
