Rainbow Six review – Clark gets his own command

📖 Introduction

⚓ This review is part of our guide to Tom Clancy books in order — every Ryanverse novel in publication and story order, with the honest answer to where to start.

By 1998 Tom Clancy had made Jack Ryan the President of the United States, which is a problem for a thriller writer. A President cannot go anywhere interesting. He gets briefed, he authorises things, and the actual work happens several rungs below him where the reader can no longer follow it.

Rainbow Six is the solution, and it is a good one: get out of the White House entirely and go where the work is. John Clark is handed his own command — a multinational counter-terrorism unit assembled from the best operators several allied countries are willing to give up, based in England, deployable at very short notice, and answerable to almost nobody.

The result is the most structurally peculiar book Clancy wrote, and one of the two or three most enjoyable.

🧠 The story

The first half is essentially an anthology. Rainbow forms, trains, argues about doctrine, and then gets called out: a bank in Switzerland, a hostage situation in Germany, a theme park in Spain. Each incident is a self-contained operation, planned and executed over a chapter or two, and each is built with the meticulous care Clancy reserved for things he genuinely understood — approach routes, entry timing, who covers which door, what happens when a plan survives contact for about nine seconds.

Taken on their own these sequences are the best pure procedural writing in the later novels. Taken as a structure, they are odd: you are two hundred pages into a thriller before you learn what the thriller is about.

Because the incidents are connected. Somebody is manufacturing terrorism, and doing it specifically to demonstrate that the world needs better security. Behind that sits the Horizon Corporation and a group of people who have arrived, by a chain of steps each of which sounded reasonable to them, at the position that the planet would be improved by the removal of most of the humans on it. Their instrument is a modified virus called Shiva, their delivery mechanism is the Sydney Olympics, and their follow-up is a vaccine that does not do what it says.

It is an enormous swing, and it should not work as well as it does. The reason it does is that Clancy plays it entirely straight and entirely procedurally — the conspiracy is a project-managed operation with budgets and staffing problems, which is far more unsettling than a lair would be.

🎭 Characters and craft

Clark in command is the best use anybody found for the character. He is not the avenging figure of Without Remorse here; he is a middle-aged administrator who happens to be extremely dangerous, spending most of his time on personnel, politics and paperwork so that his people can do the job. Clancy clearly enjoys writing him, and the relationship with Domingo Chavez — his subordinate, and by this point his son-in-law — gives the book its warmth.

The team itself is where the book shows its age slightly. A multinational unit means a large roster introduced quickly, and several members never become more than a nationality and a specialism. Clancy is much better at the collective than the individual here, which is fine for the operations and thin for everything between them.

The villains are more interesting than the usual Clancy antagonist because their logic is internally consistent. They are not cackling; they are certain. That certainty, arrived at in comfortable rooms by people who have never had to look at the consequences, is a recognisably modern kind of danger, and the book got there early.

The climax abandons the tactical precision of the earlier operations for something considerably broader, and your mileage will vary on it. It is the one point where the book stops being a procedural and becomes an adventure.

👨‍👧 The dad perspective

This is the most straightforwardly fun book on the Clancy shelf, and after the weight of Without Remorse that is a relief.

The appeal is team competence. A unit that trains properly, trusts each other, plans carefully and then executes — the deep satisfaction of watching a group of people be good at something together. There is a reason this specific fantasy became a video game and then a genre. If you have ever enjoyed a heist film for the planning rather than the heist, this is the same pleasure at novel length.

Reading commitment: long, but the episodic first half makes it unusually easy to put down and pick up. Each operation is a self-contained unit of two or three chapters, which suits an evening that might get interrupted.

Audiobook: good, with the caveat about the large roster — keeping fourteen operators straight by ear takes some concentration. Audible’s 30-day trial covers a book of this length; check what is in the catalogue on the day rather than assuming.

Age guidance: 16 and up. Considerably more approachable than Without Remorse — the violence is professional rather than personal, and there is nothing here as morally uncomfortable. The hostage sequences are tense but not gratuitous.

The games note: the video game was built alongside the novel by Clancy’s own studio, and the two share a premise and very little else. If your route in was the games, the book will feel both familiar and completely unlike what you expected. Our Splinter Cell series review covers the other half of the Clancy gaming legacy.

✅ Pros & cons

Is the Rainbow Six book worth reading?

Yes — a 5 out of 5 for us. The structure is odd, with a first half of self-contained operations before the real plot arrives, but Clark commanding a team is Clancy doing what he is best at, and the individual missions are superbly built.

Is the Rainbow Six book connected to the video games?

Directly, at the start. The game was developed alongside the novel by Red Storm Entertainment, the studio Clancy co-founded, and shares its premise of a multinational counter-terror unit. The two stories diverge quickly, and the franchise Ubisoft runs today has little to do with the book.

Do I need to read Without Remorse first?

Not required, but strongly recommended. Rainbow Six works on its own, and it is much better if you already know what John Clark cost to make. Without Remorse is the origin story.

What is the plot of Rainbow Six?

Clark forms Rainbow, a counter-terror unit that responds to incidents across Europe. The incidents turn out to be connected, and behind them sits a group planning to release a modified virus at the Sydney Olympics and follow it with a fake vaccine. Stopping that becomes the second half of the book.

Is Rainbow Six suitable for teenagers?

It is more approachable than Without Remorse — the violence is tactical rather than personal and there is no revenge material. We would still say 16 and up, mainly for the sustained hostage-rescue sequences and the scale of the threat.
