Valid for the USNR as well. E-side, there seems to be a big push to get butts in the seats, whether there's productive work for them or not. O-side, you better have a billet in mind.
Location is the problem, again. It's hard to expect guys to exceed minimums - or make best use of reservists - when the only place they can drill is way the hell far away from where they live. Case in point, I fly E-2s for my day job in Pax, and drill with the E-2 SAU in Norfolk, which is a 3.5-hour drive each way. Can't exactly drop in as-needed or take advantage of an off afternoon to get a drill in.
