The haircut is what was tolerated in the late 70s to early 80s.
The fatigues look like the old cotton pants with the “new” permanent press shirt.
It wasn’t “tolerated” in any unit I was stationed in, and I wasn’t exactly in a STRAC infantry unit, I was in intelligence. As for the fatigues, you’re probably right. I was forced to buy BDUs right before I got out but only wore them to one formation. Did not like them.
