I would like to think of the personnel gurus as my own personal gurus, but that is another thread all together.
When you say "allowed to take leave" are you taking official leave that you are getting charged for, or basket leave? If it's basket leave, then you will still have the days on your LES. As for official leave, I am told is that you can't take leave while on reserve active duty orders. Either it's not allowed, they have don't have a system in place to account for it, or they are full of B.S.
BTW, this is a Navy Reserve unit.
