Cpt. Bruce Crandall was the pilot that was referenced in Gen Moore's book and the movie. The story of LZ X-Ray and the troopers that fought there were legendary to us new "FNG" Skytroopers that came to VN later. I met Gen Moore at a book signing in San Antonio, TX. He still impresses the hell out of me.
Normally, I'd sign my name as well as units but being as this is a BDSM site I'll not do that, so here's who I served with:
1/5, 1st Cavalry Division
AnKhe, Bong Son, RVN 1966-67
18th Brigade, IFFV Nha Trang, RVN 1967-68
