Sgt Grit,
Attached are three pictures that I just came across yesterday while looking through old photos. The top photo is of me marching as the guide next to Sgt Mazenko on graduation day (Oct 27, 1981 – Platoon 2063 Parris Island).
Back then for graduation we marched in Columns of two with the SDI out in front and the "junior" DI's each marching in front of a section of the platoon, but not sure how it is done today. I was a squad leader at times during boot-camp (got fired several times, by Sgt Ishmail and always reinstated by Mazenko, but that is a story for another time), but never served as guide, so when Mazenko selected me as his guide for Graduation Day, I was all filled up with extra pride. My dad took the photo, but I did not know he took it – must have zoomed in, because he never got that close to the parade deck as far as I know.
