Sergeants as mentors and babysitters? This is not my Dad’s army, lol!
He didn’t say they were nice babysitters.
Yes its the job of the sgt’s to keep the lower ranks on task and out of trouble.
Yet your dad’s Army would very likely have been able to spot the issues, and deal with them effectively. No, not by “mentoring” and “babysitting” for sure. At least not the way the terms are used today.
