Yeah, the 4-5 Quonset huts that I moved through in 1970 (I lost count). I remember the DI quietly pronouncing “platoon 1034 on the road” in a conversational tone and everyone in the huts was supposed to hear that from their bunks and begin scrambling into formation. Not responding would get exactly the reaction shown on the video.
The quonsets we lived in at ITR on Pendleton were later used to house the Vietnamese refugees in 75. All of the quonsets and concrete washracks dated from the 20s and 30s and were used by almost 50 years of recruits.
One of my buddies’s dad was a DI. Very much the absent dad. But I talked to him in the early 80’s and they had pretty much been stripped of the ability to hit recruits. He said he didn’t need to hit them. He said “I have the ability to send them home to their families in disgrace. I’ll make them go all the way through boot camp and then sit with their familes in the bleachers wearing civies and watch their buddies graduate”. Pretty sadistic/
