I come from a family of Jarheads.
Grandfather was Marine Infantry WWII all across the Pacific. Iwo Jima, Guadalcanal, Midway. Didn't talk about it at all.
Dad was Marine Pilot in Viet Nam. Three tours.
I was a Marine Flight Engineer on KC-130F/R '92-'00. Saw all the finest places a Marine can visit...
One of my sons was a Marine Flight Mechanic on KC-130J '12-'17.

Love the Corps, Love this country.
I think everyone should be required to enlist for two years. Teach them how to be an adult. If you like it, stay in and learn a trade. Just my $0.02.
