When I was in the Army we lived in pre-WW-I German barracks. They weren’t half bad, a lot better than the cookie cutter U.S. wooden squad bay style barracks, pre-WW-II.
Guy I know had occupation duty in Japan, circa 1946. They stayed in Japanese Army barracks. He was surprised how much better they were than U.S. barracks.
Of course, the U.S. troops in question are Air Force, their standard is something like a Marriot, with a better restaurant and spa.
Not these days. We do tent cities and temorary structures.
We do believe in good chow halls, though.
