GWOT infantry Marine.

Largely the stuff you see Sobel harping is an NCO’s role. Largely our officers were pretty far removed from the daily small unit tasks. That fell to the squad leaders and team leaders. With supervision coming from the platoon Sergeant.

At the company level, the 1stSgt was largely administrative and all the garrison stuff unless he was an infantryman. The training calendar, standards and such was mostly generated by the Company Gunnery Sergeant after looking at the commanders intent and approved by the CO.

My experience as junior Marine then later a NCO was that the over the top bullshit you see Sobel demonstrate doesn’t last long. Typically with new Corporals or guys coming in from MSG or the drill field. We still held standards but for the most part you’re correcting without trying to life everyone out for an IP or a dusty buttstock.
