Dear Sgt. Grit,
I am one of your customers! I served in the Marine Corps from June 1952 to June 1955, with 15-months service in Korea. I joined on my 17th birthday, was out on my 20th, and was a Sgt. at age 19.
Attached is my "Old School" boot camp picture. I am on the top row, last on the right.
Semper Fi!
Bob
