My DI in Army Basic was Sgt. Golding.
We learned early on that he was doing the best he could to make us the best we could be. I know it sounds like a recruitment poster, but it was true.
I am sure he had to "dress down" someone in the platoon, but I do not recall the event. He did yell at those not moving fast enough...telling them to "pick it up" or "hustle" or what ever by name. And he would be on your tail till you didn't give it your all. But I don't remember him ever "shaming" one of us.
We has a guy in our platoon, named Slywinski or something. The DI called him Slick Whiskey. The guy was thin and could never stay in step. The DI would remind him regularly to pay attention. One day, Slick Whiskey broke down and started crying. The DI pulled him out of ranks and gave us an About Face. I peeked and he had his arm around the guys shoulder, I guess explaining what the DI's purpose was with training new troops.
I don't know if he did any good, but Slick Whiskey bucked up and did somewhat better....and there were very few NCO's or Officers I came to respect more than Sgt. Golding.
This was in June of 1965.
