Thank you, from me personally, to all who served in Vietnam.
Our 10-man unit had an M60, two M79s, seven rifles, about a dozen LAAWs, frags, smokes, C4, Claymores and Kabars and two PRC25s to pull the chain for heavy hitters...so we were in pretty good shape with firepower if we ran into a larger enemy force, which we did a few times.
Our sole NVD was a Starlight Scope, big and clunky, and frankly we could see better in the dark without it. Our prime operational time was at night; laying low near a ville or hamlet during the day and going mobile at sundown, moving in stages to checkpoints and finally getting to a night ambush site in full darkness where we would remain until about an hour before dawn. We'd sometimes run a Kilo Tango (Kill Team) from the main ambush site, usually three guys with rifles, frags, Kabars and one of the radios...or broke the whole team into Alpha and Bravo units, setting up two night ambush sites, with each to run react or act as blocking force for whichever unit had contact. It was a pretty effective way of doing things and we were quite often able to surprise them as they moved along trails at night.
If we had contact, we'd move again afterwards to a secondary ambush site, provided we had enough remaining ammo. But if we had to medevac more than two people (3 people gone was 30% casualties) we'd abort offensive ops and try to get to a more secure position to ride out the night.
Some of the battles fought during that war are incredible. Battalions fighting off and beating regiments, small teams taking on platoon and company size units. The advance's in equipment and tactic's, and the advancement of U.S. special ops and reconnaissance is simply, amazing.
I've been on a reading kick on LRRP's and the MAC-V-SOG Recon Teams, everything I've been reading is mind blowing, especially when you consider the technology they used vs ours now. It's very humbling to say the least.
