What regulation or policy addresses if you are allowed to drink during Reserves AT?

The entire active duty DOD is on Title 10 orders.

Ranger School has a bar, SF association has multiple bars, OCONUS locations have bars, Team rooms have bars, Air Force squadrons have bars, they even have LTs tasked with restocking the bars. There are Officer and NCO clubs that have bars. Nothing says you can't drink on Title 10. I'm on Title 10 and I'm enjoying a delicious German Heffeweissen right now, straight from Bavaria. If you couldn't drink as a Title 10 Soldier we wouldn't have a Class VI, Class VI being a class of Supply.

He can tell you not to drink as the commander but the entire active Army is on title 10 orders.

I've never looked it up personally, but have been instructed by BN CDRs and Training Exercise CDRs that alcohol is against GO#1 as the training area(s) are considered "deployed" locations. And that, if alcohol is to be consumed, an ETP signed by a GO has to be in hand. Personally, I feel that it's only 2-3 weeks of no beer. I can wait that long to have a beer. Also, if your Commander says no drinking, then no drinking is allowed since that would be a valid and legal order.

Title 10 has nothing to do with it. Every duty status in the Reserves is T10, they don't have another kind of funding like the Guard.
Annual Training, Drill (IDT, BA, whatever you want to call them) all fall under General Order #1 (GO1).
Typically every 2 star everywhere in the Reserve components will publish a GO1 update every year.
Somewhere in the OPORD or FRAGO about your AT there is an enclosure of GO1, probably signed by MG Susan Henderson or her predecessor, that says, among other things, no drinking during AT.
And GO1 is punitive: grabbing a beer or two during AT is not worth the embarrassment of having to make a rank back a second time.

Commander’s discretion. Sometimes the Army is fun and sometimes it’s not.

There may be a policy memo for your unit when you are on orders that that really isn't a thing. You may have to ask for the Policy Memo if they are not posted.

I do not know of any regulation that prohibits while at Annual Training. However, it appears that you commander does not want her SMs to drink. I think she is a coward by passing it off to Title 10. If her policy is not to drink at AT, she should write the policy letter and post.

George Washington that! And —-> in the spirit of the first Commander-in-Chief & POTUS some workaround Rx semantics: “bottled, flasked, used for special (medicinal) purposes.“ Cheers - if not now then @ the AT after party.

On the ANG side there is AFI 1-2, Commander’s Responsibilities, outlining broad responsibilities and expectations across the entire organization and formation. Discipline, physical well being, general welfare and quality of life are a few areas that directly affect service members. As such, commanders at all levels are charged in using discretion, as others have mentioned in this thread regarding alcohol policies, which should promote a healthy command climate either way.

You do understand that the CO can order NO Alcohol during training/training event, etc.
