We can’t forget the Drill Sergeants
One of the highest honors for a noncommissioned officer is a spot in Drill Sergeant Academy. Only the most qualified NCOs are chosen to attend Drill Sergeant Academy, where they are trained to fulfill a role of utmost importance. Drill sergeants teach new recruits every aspect of Basic Combat Training, which means they have the great responsibility of shaping civilians into the best Soldiers in the world.

ARMY BARRACKS 
Fort Jackson, June to Aug ’70. B-8-2 located on tank hill. Parallel bars, low-crawls on the canvas before chow and marches to the rifle ranges. Sgt. Jones, Kreder, Shivers and Pacquette were drill sergeants. We had RA’s, NG’s, ER’s and US’s. I was the latter! Lived in the WWII era wooden barracks, torn down now. I see satellite views of tank hill and think, I was there!
Fort Jackson. A-2-1 King of the hill. 1967.
Took my basic training at Fort Knox Kentucky.
August 1963
D-15-4
