I do remember a couple in my squadron when I was young USAF 1-striper KellyinAvon back in the day. I’d have never known it except for a classified briefing one day and folks without a security clearance had to leave.They have for years. They serve honorably and don't even get a pat on the back.
I'm sure many veterans here served beside a non citizen soldier.
Coincidentally that was probably my first, “OH WOW THIS **** IS REAL!!” moment at an operational unit.
To the Military BS stories thread!!
