Factual error: A bunch of troops are in heavy camouflage in helicopters, going to an assignment. The officer in charge tells them to take their dog tags off and empty their pockets of anything that could identify them. This is silly: first, in troop helicopters, the troops wouldn't be able to hear the officer's voice - it's too noisy - and second, this would be ingrained in them, to remove dog tags etc, and would have been done back at the base, before they left.
Factual error: On the sniper range in a close up of Chavez's finger going on to the trigger, his placement is completely wrong. He's wrapped his finger around the trigger instead of using only the pad.
Factual error: On the Sniper range the reticle used in Chavez's weapon is completely wrong. It would have mil-dots on both the vertical and horizontal lines.
Factual error: When Jack Ryan arrives in Colombia you can see clearly a street name on a plate. That's not a Colombian street plate and it's a Mexico City street.
Factual error: When Willem Dafoe is targeting the villa with an air-launched bomb, the first time you see the F-18 in flight, it has a drop tank, but no bombs.
Factual error: When Dr Ryan first arrives in Colombia and takes a government vehicle through town, he rolls down the window. The DEA agent says, "Don't do that because it's a bulletproof vehicle." In reality, you can't roll down the window on an armored/bulletproof vehicle. (00:50:00 - 00:55:00)
Suggested correction: A quick Google search shows that some armored cars have roll-down windows and some don't. Maybe this one did.
Factual error: It wouldn't have mattered that Ritter had his "autographed get out of jail free card" given to him by Cutter or authorized by the President, it was still an illegal operation that Congress didn't know about. Anyone involved in it would be going to prison regardless of position.
Suggested correction: The point Ritter is making is the operation was personally authorized by the President behind closed doors. If Cutter and Ritter were arrested for their involvement, they would be pardoned by the President. The President of the United States has the authority to pardon someone even before they have been charged with a federal crime, as Gerald Ford did for Richard Nixon. Jack doesn't have this protection because he is to be the scapegoat if the scandal is exposed.
