You should absolutely document the session. Here is a short sample to get you started:
________{insert Rank/Name}, on ________{insert date}, we discussed your potential reenlistment. Your current ETS date is:___________{insert date}, your current reenlistment date closes
on or about ________{insert date}. Should you choose not to reenlist within your reenlistment window which ends on or about ________{insert date}. There is very little chance you will be allowed to reenlist
as the Army is changing reenlistment requirements to meet drawndown requirements.________{insert date}.
Should you choose not to reenlist I would encourage you to aggressively prepare and execute a plan of action that allows you to take maximum advantage to any and all Army programs that can assist you
in the transition process.
