Wow, lots of pics there. However, Bearcat 15, the AH-1G with 15 on her side is a US Army Aviation Test Board bird and never flew in Vietnam.
Here's a few from the US Army Aviation Museum archives.
2/20th ARA (Arial rocket Artillary). At least one of these birds flew at Ia Drang in November of 65. These are all UH-1B's as you can tell by the nose mounted pitot tube.
XM-3 armed Hog ship
This bird carries the Maxwell system which consisted of 12 2.75 inch rockets and an in country mod to carry 1 ss-11 french anti-armor/bunker buster missile outboard.
Not a great pic, but here's the system with a SS-11 in place.
This is a lightening bug ship used for perimeter night security. The light is from a tank. I can't remember the model.
Finally, one that's a little more personal. Here's my dad on a gun run in 69.

Since this topic is such a big hit in Google results I cleaned it up a lot, deleting posts with broken images and attaching images that were still intact to their respective posts. This is all some valuable history that should be preserved.
