From my memory of four months in Turkey and tent city life, the AC could keep the tent at a brisk 60 degrees on the hottest days. We had our tent carpetted. For me, that was five star accommodations.
I slept in a pup tent while on exercises in Korea, but my “office” (a 5 ton expando-van) was air-conditioned and attached to a dozen similar trucks with a flat bed acting as a boardwalk between them. The general officer’s van always had coffee, lemonade and cookies.
