The Sum of All Fears
The Sum of All Fears is the 2002 thriller which is the fourth feature film adaptation of the Tom Clancy Jack Ryan novel of the same name. While the plot follows elements of the novel, the film features Ryan at the beginning of his CIA career. Ben Affleck takes over the role of Ryan, as he is assigned to investigate the disappearance of three Russian nuclear scientists. The film was directed by Phil Alden Robinson (Sneakers) and the cast included Morgan Freeman, Liev Schreiber, and James Cromwell. A fifth feature film adaptation of the character, Jack Ryan: Shadow Recruit, was released in 2014 and starred Chris Pine as Ryan.
The following weapons were used in the film The Sum of All Fears:
The M4A1 carbine appears in the hands of US military personnel several times during the film, first in the hands of guards outside the Mount Weather Emergency Operations Center where President J. Robert Fowler (James Cromwell) is taken during a nuclear attack drill at the beginning of the film, then in the hands of (actual) US Marines who rescue President Fowler after his motorcade is hit by the shockwave of a nuclear bomb blast in Baltimore, Maryland. In both instances, the M4A1s are equipped with Trijicon RX01 red dot sights. Since the production was not allowed to bring real weapons from the US to Canada (where the movie was filmed), the Marines' weapons seen during the President's rescue were replicas.
Some of the Marines that rescue President Fowler can also be seen carrying M16A2 rifles. These also were replica weapons.
M203 Grenade Launcher
In the scene where President Fowler is rescued by the Marines, one of them can be seen with an M203 grenade launcher mounted on his M4A1 carbine. Another Marine can be seen with an M203 mounted on an M16A2 when the President arrives at Andrews Air Force Base to board a National Airborne Operations Center E-4 aircraft.
At one point in the film, Jack Ryan (Ben Affleck) and John Clark (Liev Schreiber) go to Ukraine while searching for a group of missing Russian nuclear scientists, Clark carrying an M1911A1 fitted with Pachmayr grips as his sidearm and an extra one which he gives to Ryan. The two later end up in an armed standoff with a pair of guards, though are able to force the guards to surrender without a shot being fired.
Norinco Type 84S-2
During the standoff mentioned above, the Ukrainian guards can be seen armed with Norinco Type 84S-2 rifles fitted with AK-74 style muzzle brakes, likely to pass as AKS-74 rifles though are easily identified by the hooded front sight, metal 5.56x45mm magazines and right-folding stocks. After the guards surrender, Ryan and Clark take their rifles and their boots, leaving them unable to pursue the protagonists in the snowy terrain.
"Pre-B" CZ 75
Near the end of the film, two Russian FSB agents (played by Quebecois policemen) can be seen chasing down and then killing a member of the group responsible for the bombing of Baltimore and nearly triggering a nuclear war between the United States and Russia, the agents being armed with "Pre-B" CZ 75 pistols.
The Israeli Air Force A-4 Skyhawk seen in the beginning of the film is armed with an ADEN cannon.
The Phalanx CIWS (Close In Weapons System) is activated when the renegade Russian planes attack the USS John C. Stennis aircraft carrier. The CIWS destroys several of the cruise missiles fired by the bombers, but some still manage to get through and damage the ship.
