Not worth another topic but this book review gives food for thought.
On the day in 1967 when Hamilton Gregory reported to a Tennessee induction center to begin his service in the U.S. Army, a sergeant presented him to another young man who was also headed to Fort Benning, Georgia, to start basic training. The other new soldier’s name was Johnny Gupton, or so Gregory calls him. “I want you to take charge of Gupton,” the sergeant told Gregory. Before they boarded the bus to the airport, the sergeant handed Gregory Gupton’s paperwork along with his own, to carry on the trip.
In the next hours and days, Gregory discovered why the sergeant had put Gupton in his care. Gupton could not read or write. He didn’t know his home address or what state he was from, so he could not send the pre-stamped postcard the new recruits were given at Benning to tell their families they had arrived. He didn’t know his next of kin’s full name, didn’t know that there was a war in Vietnam, and couldn’t tie the laces on his combat boots. [/quote https://mwi.usma.edu/book-review-mcnamaras-folly/
