My Grandson Left For Navy Boot Camp

I cannot imagine what today's boot might be like. I went, spring of '68 arrived about 26-28 May. I've read, or maybe YouTube that modern sailors get a fair amount of small arms hands on range training. I got nothing but part of a day, firing an M1 Garand, prone only, at Camp Elliott, San diego. Ironically, a couple years later, I would spend 4 years at NAS Miramar, right across hiway 15 from there.
I had very few interactions with Navy and Air Force while I was in the Army, but when I did.....
They would always make a beeline to my M16A.
To the OP, congrats on your grandson.
Just remember, where jump school is concerned if at first you don't succeed, you won't get a second chance!
