I enjoyed it. A small, international, top secret counterterrorist organization may be a bit of a stretch, but overall it was a decent book. It was a little heavy on the military jargon, and it the story could have been told in maybe a couple hundred less pages. For the record, I’ve never played any of the numerous video games this book has spawned.

First, I enjoyed this novel. It's garden variety Tom Clancy, including stereotyped characters that are all Overachievers, Republican, hold at least a Master's Degree in Something, and are Paragons of Physical Fitness...the story development and pacing, again, are typical Clancy.
All of that said...I wish one of his editors, preferably three or four novels back, would've had the temerity to say, "You know, Tom...that's the third time in as many sentences your character has clipped a pronoun or article in his speech..." Here's a typical exchange between two of his characters ( pick any one of his novels ):
"Hey, Bud; how's it hanging?"
"Good. You?"
"Been worse. Getting reassigned in May."
"Going where?"
"Pentagon. Driving a desk. Could be worse."
It would be so simple! Just insert the pronoun 'I' about one hundred times throughout the typical, thousand-plus page book, along with a few articles such as 'the'...I served in the U.S. Army for more than a few years, and can personally attest to very few guys who actually talk that way, and ZERO females. This may come across as cheap nit-picking to some avid fans, but it is my biggest pet peeve: after two or three pages of "sociology block" narrative, you long for that "oasis" of conversation, and when it finally shows up, it's invariably two "Ranger Ricks" waxing macho!
I guess it struck me as a little ridiculous, too, when Clark's protege Ding Chavez, who early in this novel is depicted as running somewhere on the order of twenty miles a week is chided by his wife for eating a decadent breakfast of eggs, bacon and grits (!) Tom, you don't do women particularly well...especially one who's apparently oblivious to her husband's exercise routine. Stay away from domestic/bedroom scenes, just as Stephen King should stay away from UFOs and the military. That advice, while certainly unsolicited, is free, since you've apparently long since cowed your editors into submission.
If the above criticisms don't get you wrapped around the axle, this one is a good read.

I ENJOYED THIS BOOK, ALTHOUGH IT COULD HAVE BEEN SHORTER. CERTAINLY, SCARY....A MUST READ IF YOU ARE A CLANCY FAN, OTHERWISE, READ HIS OTHERS FIRST.

This book sticks with you, every now and then, a segment of this book will flash in my mind and I have to stop and think where did i read that from and sometimes it comes from Rainbow Six.

What makes this such a good book is the games that followed it. Rainbow Six Las Vegas is one of my favorite games, and one of the reasons for that is because Rainbow Six was such a good book.

This book is led by John Clark and not by Jack Ryan and Clark delivers this book. The opening of this book is one of the best openers of the Clancy novels. The opening tells and sets the setting of the rest of the book.

John Clark and Ding Chavez are in an airplane that is about to be taken over by terrorist and these two take out the terrorist very easily. It sets the pace of the entire book, one of non-stop action and rescue.

Clancy shows that such people as Clark and Chavez are needed in this world to stop terrorist and terrorism. Clancy's books tend to tell a story that reflects modern day life and in the age of terrorism and before 9/11 this book was somewhat prophetic on what was/is needed to deal with terrorism.

Clancy delivers in this novel.

This is the first Clancy book I've read. I really like it. Great story with great attention to detail and knowledge of military specifics.

Though I enjoyed reading it, I knew that in the end the good guys would win but I was hoping that it would have been a little more substantive than it was. I guess, taking out the eco-terrorists was all just a little too easy for my liking. Still, very fun to read. Despite its length, the read is also very fast.

John Clark, ex-Navy Seal and now a covert operative with a past that is best forgotten, is the commander of a newly formed elite international anti-terrorism group known as the Rainbow Team. As he takes his new assignment, the action begins faster than he could possibly have anticipated when the plane he and his longtime sidekick Domingo Chavez are riding in is hijacked over the Atlantic. The hijackers are overcome and this begins a sequence of terrorist acts that are brutal, yet seem to have no overall purpose. Disparate and dormant groups are suddenly active, yet there appears no reason for it.
The reasons are far more deadly, an ex-KGB operative is behind the activity and he is the front for a deadly game where a group is plotting to unleash biological entities that would be by orders of magnitude the greatest mass murder of all time. If their biological weapons work as planned, they would kill nearly every person on Earth. The trail finally leads Clark's team to a major installation that the terrorists have created in the jungle.
As is almost always the case with a Clancy novel, the descriptions of the action are what makes the novel such a dynamic read. For if you were to stop reading for a moment and ponder the events, the improbability of them occurring would no doubt overwhelm you. Once I started reading it, I found it very difficult to put down, losing a lot of sleep before turning the last page.

Probably Clancy's worst book. I get the feeling he's getting a little thin on ideas.

this book is su profesional! i like it how he makes everything so detailed and realistic, it's obvious that he made some research and you just got to respect that. well written too.

I think Tom is running out of ideas, the concept was excellent but larger than life counter terrorist troops can only go so far. Interesting but not as compelling as some of his earlier work.

Rainbow Six is one of Clany's best in my opinion. It is quite detailed like all of his books, but not quite so technical in regards to weapons. Instead the details make the story more tangible. The story lines seem very possible and thus are quite frightening at times.

Rainbow Six-set a new standard for himself.

I am in the middle of reading Rainbow Six and I already think it's one of the best I've read.
