Is there a current regulation for distance having to drive to drill and what is due the service member?

This move has been in the works for over a year. I was not part of the unit during the transition or talks. I am coming in as a newly hired RNCO. Ready to go to bat or do what I can for my troops.

32 CFR 100.6.
(e)Reasonable commuting distance. The maximum distance a member of a Reserve component may travel involuntarily between residence and drill training site, in accordance with § 100.5(b)(1). This distance may be within:

(1) A 100-mile radius of the drill site that does not exceed a distance that can be traveled by automobile under average conditions of traffic, weather, and roads within 3 hours. This applies only to those units that normally conduct four drills on 2 consecutive days during the training year, if Government meals and quarters are provided at the base where the unit drills. (The provisions of this paragraph shall apply only to those individuals enlisting, reenlisting, or extending their enlistments after November 1, 1972.)

(2) A 50-mile radius of the drill site that does not exceed a distance that can be traveled by automobile under average conditions of traffic, weather, and roads within a period of 1 1/2 hours.

I don't know about National Guard units though.

I have never heard of an Army Guard unit providing lodging other than a tent or an armory. The Air Force side normally provided a hotel for their folks over 50 miles. I was always over 100 miles and just paid for a hotel room. I did the armory for years, but that wasn't conducive to much rest at night. Maybe a little pressure on your command to help these soldiers out. Can't be good for retention.
