Jack Ryan's foiling of the assassination attempt in the beginning of the book is acknowledged in-universe.
Later, he scares the piss out of the psychopath who's been gunning for him in the whole book, and Sergeant Major Breckenridge gets a CMOA for making sure Jack doesn't cross the Moral Event Horizon.

Special Agent Patrick O'Day takes down some terrorists trying to kidnap Jack Ryan's daughter, and the Secret Service get theirs by killing the rest of them in platoon-level numbers. When the terrorists attack Giant Steps, Agent Don Russell has less than a second of warning. Armed with a 9mm pistol, he takes down three AK-toting assassins in seconds, and nails a fourth in the knee as he goes down. O'Day, caught inside with a horde of kids, manages to convince the hostiles of his harmlessness and then take them down with no collateral damage. His real CMOA? A "See you around, champ" to the deceased Russellnote They'd been discussing setting up a shooting competition to see who was a better shot. O'Day acknowledged that Russell was his superior after reflecting on the crime scene.
Jack himself gets one for his Rousing Speech, in which he calls out the nutcase who tried to use biowar on his country and rats out his evil scheme to the world. He also manages to make the Smug Snake Indian Prime Minster realize she pissed off the wrong guy. And it would be wrong not to mention the conclusion of the book.
The 15,000 National Guardsmen ripping apart 2 UIR army corps. The National Guardsmen are reservists, while the Army Corps are professionals who've been training pretty hard. They also outnumber the Guardsmen by almost 6 to 1. The UIR doesn't stand a chance.
