During the introductory sequence, the fictional F/A-37 "Talon" fighter piloted by Lieutenant Kara Wade (Jessica Biel) is fired on by antiaircraft guns, including a 40mm Bofors gun in a single mount.
M61 Vulcan cannons are presumably mounted on the various US fighters seen during the movie, but are also seen clearly; several appear in the introduction in M167 Vulcan Air Defence System (VADS) towed mountings, while others are visible in Phalanx installations on the the carrier USS Abraham Lincoln.

Note that the M61 is not firing blanks in this scene, as no spent casings are coming out of the chute on the side of the gun; the muzzle flashes are post-production CG additions.Error creating thumbnail: File missingThe white fire control radars of two of the Abraham Lincoln's three Phalanx installations are visible to the left and right of her foredeck.
M16A2 Rifle
The M16A2 rifle is the standard weapon of US military personnel, most notably the US Marines on the Naval Vessels.
The Chinese AK/AKM variant, the Type 56 (and 56-1 the folding stock version) are the most commonly seen AK47/AKM rifle in movies and television (at least those done by U.S. Production companies). The Type 56 (full stock) version is commonly seen in the movie, usually in the hands of terrorists of many different stripes. Terrorist guards from several organizations are seen wielding the weapon in Rangoon, Islamic Extremists in a mountain fortress in Tajikistan, and North Korean Soldiers.
In addition to the many Norinco Type 56 Chinese AK rifles, terrorists are also seen wielding what looks like original milled receiver AK-47 rifles with original front sights (not the hooded Type 56 sights). However, being how 'new' they look, they can be the third pattern AK-47 "Legend Series" rifles imported by Poly Technologies, Inc, between 1988-1989. Those were high end identical clones of the original AK-47 rifles but very few were imported.

Though the official Colt 733 was 11.5" we see 10" M16 short carbines, in the hands of covert ops thugs in Alaska.

A North Korean marksman with the group tasked with tracking down one of the pilots uses an SVD Dragunov sniper rifle; another is later used by an officer at a border checkpoint.
A curious thing is that all the North Korean Troops carry the Yugo Zastava M70AB2 AK rifle (with a flashlight taped to the front hand guard).

A Black Steyr AUG is held by a black ops guard, Gannon tell him to set it on the ground. When Gannon is ambushed, the guard picks it up again, but is shot by Gannon. Steyr AUG rifles can also be seen in the Alaska Base Armory.
An M4 Carbine is used by a guard to ambush Gannon. Also M4s are seen in the Alaska Base armory against the wall and being handed out to guys sent to kill Gannon.
