This is intended to be a factual account of helicopter and infantry actions during Vietnam. Wherever possible, the names of the people are included, as well as where they were from. This is not your typical "war story," where everyone is heroic and everyone comes out alive at the other end. This is messy, gritty, bloody and painful.
The books starts with the author at US Army OCS, deciding he wants to try for flight training. Not only does he get flight training, he ends up getting the ride of his choice: the OH-6A Cayuse (known in the civilian sector as a Hughes 500). If you've ever seen the original Magnum PI, you'll remember that his friend, TC, flies around in a small, fast, agile chopper. That's (usually) a Hughes 500. It would make sense, as TC flew choppers in Vietnam.
The author has nothing but praise for this fast, agile, tough little aircraft. Armed with a crew chief in the back seat, firing a .50 caliber M-60, and a hard-mounted minigun (7.62 mm, 6-barrel, Gatling-style, capable of spitting out 4,000 rounds / minute), he did a lot more than just scout. He flew fast and low, looking for footprints in the mud, disturbed grass, anything which would lead him to where the enemy (whether VC or NVA) was moving or hiding. He got a lot of choppers shot out from under him. He was wounded on multiple occasions (including, quite literally, shot in the a**, with a tracer no less). When you're flying low over active combat zones, you will get shot at, you will get hit and people will die. He makes a point of giving name, rank and hometown, where possible, of everyone he works with who doesn't come home alive.
I spent my time in the Air Force working on F-16s, not choppers. I have seen these birds up close; an Army unit, still flying these things, deployed to my base in Utah for a week. I can attest to the fast that they are remarkably small, very fast and nimble. And yeah, being military folks, the crews really do speak that much jargon.
The tactics used make a lot of sense. The aeroscout (the OH-6A) skims the terrain, looking for Bad Guys, shooting it out with singles and handfuls and dropping smoke grenades on the groups / facilities they can't take out themselves. An AH-1 Cobra fires rockets on whatever they designate. If the Cobra can't take it out, they can call a Forward Air Controller who can bring in anything from a couple fighter jets with napalm to a B-52. If there are Bad Guys to capture or a facility to investigate, "slicks" (Hueys) arrive with men to capture, investigate, etc.
In the Civil War and WW I, if you needed to move a lot of people around, they marched. Or, if they were lucky, they could ride the train or ride in trucks. That's a slow way to move people. Helicopter technology wasn't quite ready during the Korean War. Most of us have seen episodes of MASH. The piston-powered choppers of that era were great for moving a handful of people around, pretty quickly, but they were still quite limited. It wasn't until turbine engines got small enough, and reliable enough, that they could put them in choppers that chopper tech really evolved. The OH-6A, the Huey, the Cobra and the Chinook all saw combat in Vietnam; all of them are turbine-powered. That was when the tech finally came of age. We are still flying all of them, today.
Stuffing a dozen guys in a Huey and hustling along at over 100 knots, taking them from relatively safe facilities straight to areas where they know, or strongly suspect, the fight will be ... much better than marching for days or riding in a truck for hours, arriving tired and beat up and THEN having to fight.
It's rather different from the story of Vietnam most of us see / hear in the usual historical accounts and movies. Most of us get the tale that Vietnam was an utter boondoggle, a colossal waste of life and treasure. That may be the case. Make no mistake, the people over there fighting and dying didn't see it as such. They went where they were told. They developed and evolved tactics, as needed, to find better ways to fight and survive. If it was a waste of lives and treasure, blame the politicians who sent them there. The soldiers who served were doing their duty and doing the best they could with the situation they had.
There's also a lot of "local color." It's not all flying, shooting and getting shot at. The part about swallowing the toad ... unfortunately, I have no difficulty believing this. The author paints a very picture and I can see it.
I found this book to be a page-turner. But I love aircraft and reading about tactics.
