You can't just quit. This never happens: "Hey sir, I've been giving this a lot of thought. I decided that as much as I have enjoyed my last 9 years in the Army, I feel that my time away from my family is having too much of a negative influence and I need to make a change. So, this is my two week notice."
Instead, it is more like this: "Sir, here are my four memorandums that are required in order for me to leave the Army. This one is my resignation, this one is to verify that you counseled me, this one is to verify that the Colonel counseled me, and this one is to verify that I know that I have been counseled. Here is my leave form, my education counseling, my last evaluation, and my official records file. I understand that the paperwork must be in six months before I separate from the Army, so my leave will begin in July and I will be separated in September."
And then they find a formatting error or a misspelling on your fourth memorandum and the dates are no longer correct because that other guy took too long to check them. So, re-do them with the correct dates.
The pin on this smoke grenade is pretty tough to pull.
