Its interesting to read about service during WWII. Just about everyone not qualified for active combat service were involved in some way. Former Heavyweight Champions Jack Dempsey and Gene Tunney were commissioned in the Navy and taught Physical Fitness. Tunney had previously served as a Marine. Actor Robert Stack was already an accomplished skeet champion. He was commissioned into the Navy and taught aerial gunnery. And he convinced many of his skeet shooting friends to do the same.
W.D. Jones, who periodically rode with Bonnie and Clyde was doing a prison term in Texas. He wrote the War Department and offered his services to the Army as he felt they could "use a man skilled with the BAR." They were going to let him enlist until they discovered a bullet and fragments still in his chest and he failed the physical.
My own Grandfather, too old and too many kids to enlist, inspected 1911A1 pistols for Remington-Rand.
I have been retired now longer than I was in, but I would still offer my services if needed. I would most likely fail the physical at 61, but I know I could recruit or instruct, freeing up a young guy to go to sea.
I just wish we could remember that we are Americans first, last, and always and find a way to break this political and racial division and anger among us. Our country is worth the work it takes to maintain our liberties and freedom. I fear the future and the direction that we are headed.
