Regarding Ia Drang. The book "We were Soldiers Once... and Young", being made into a film, featured a young Lt. Called Rick Rescorla.

Rescorla is missing as of 11/9, he was head of security at Morgan Stanley. He lived as he had done in Vietnam. His last actions saved the lives of 2,700 Morgan Stanley employees.

God Bless.

Great work, Gruntboy!

Puff the Magic Dragon: These are actually AC-130 gunships mounting miniguns and even 75 and 105mm cannon. I know there were also Dakota versions.

Spad or Sandy refers to the A-1 Skyraider.

A thumper refers to a grenade launcher.

The Black Horse regiment was actually the 11th Armored Cavalry regiment.

I've read "We were soldiers once". Great book. Looking forward to the movie.

Since all of the questions are answered, i'll add some more facts, most of the wild weasel missions were flown by F-4 Phantom II's which gave them the nickname, WildWeasel.
:D
We have one on display at the VFW here in town, very cool jet.

9) This bombing campaign was designed to force the North Vietnamese government back to the bargaining table. Linebacker

wasn't there also a linebacker II, or was that merely a continuation of the first? (or am I just wrong?)'

Last VC must have been awarded in the Falklands, I think to a Para Major. The VC can only be awared in "in the face of the enemy", so soldiers in Northen Ireland, former Yugoslavia etc cannot qualify. Interestingly, my great, great, great uncle was awarded the VC in the crimean war.

Yes there was Linebacker II

Actually, according to the story, the last VC was awarded to an Australian soldier in Viet Nam.

A posthumous VC was awarded to Lieutenant Colonel Herbert Jones who was killed leading the 2 Para assault on Argentine positions at the battle of 'Goose Green' during the Falklands War.

Well, there you go. Learn something new every day. :)

I have a question about Puff the magic dragon.
I think there's a song with the lyrics "puff the magic dragon lives by the sea" or something like that... what's the relation with rotary cannons?

The song came first. :D

Troops named the gunships "puffs" after the song.

Not quite sure why but the ROF was so fast on these things, a solid line of tracers used to reach to the ground. Coupled with a proliferation of mind-altering drugs, someone came up with the association.

The rate of fire on the 20mm six barrel rotary cannon used in most American warplanes is around 5-6 thousand rounds a minute. Most actually fire at a reduced rate to avoid wasting ammo.

Btw, I believe these guns are also used in the Phalanx point defense systems on many NATO ships.

Anyway, I suspect that the ammo fired by an AC-130 had a much higher proportion of tracer since most action would take place at night and you kind of need to see where the rounds are going. :)
