Jack Thorpe (Michael Champion), the American terrorist, uses a Beretta 92SB as his sidearm, as noted by its rounded trigger guard. When Thorpe shows the Beretta to the guard when they first arrive at the school, it has a silencer mounted. An army infiltrator uses a Beretta 92SB at the end of the film to deliver the fatal shot to Luis.
One of the terrorists uses a Norinco Type 56-1, as noted by its hooded front sight and under-folding stock. It is fitted with an AKM-style muzzle brake, making it similar to the gun used in Heat, meaning it was a semi-auto Chinese import, converted to full-auto fire for the film and fitted with the slanted muzzle by the gun's importer.
The terrorist who commonly partners up with the other man with the 56-1 uses what appears to be a Poly Tech Legend AKS-47, a model most closely resembling a genuine AKS-47.
The belltower guards use an M72 LAW anti-tank launcher to blow up the police car. Thorpe tries to use one on the infiltration Black Hawk helicopters, but is shot to pieces by an M230 Chain-Gun from one of the Apache gunships providing cover for the Black Hawks.
The terrorists overrunning the school are armed mainly with Heckler & Koch SP89's mocked up as Heckler & Koch MP5K submachine guns. Army Infiltration members use them as well. Billy Tepper (Sean Astin) steals one from a terrorist when the Army infiltrates the school and tries to ambush Luis Cali with it, but is thwarted.
One of the terrorists is seen multiple times using an Uzi Carbine, the civilian version of the Uzi, fitted with a 16-inch barrel with a barrel shroud. It seems the armorers converted it to full-auto fire for the film. It is most notably used when Joey Trotta (Wil Wheaton) knocks out a terrorist and attempts to kill another with the the Uzi, failing as the muzzle rise, very inaccurately depicted, raises his fire to the sky, and he is gunned down by the terrorist's SP89.
The infiltration unit has two snipers armed with what looks like Iver Johnson AMAC-1500 sniper rifles. They have heavy muzzle brakes and fluted barrels. One appears to be an older spec than the other based on the different muzzle brakes.
One of the roof guards is still partially alive after being shot by the snipers, his last act being to drop an M67 hand grenade down on the infiltration unit and kill all but the leader, who is wounded in the leg.
M230 30mm Chain-Guns are mounted on Apache gunships providing cover for the infiltrator Black Hawks during the assault on the school. One of the Apaches fires it's M230 at Thorpe (Michael Champion) before he can fire a M72 LAW rocket.
The wounded infiltration unit leader gives Dean Edward Parker (Louis Gossett Jr.) his Browning Hi-Power sidearm when he cannot go into the building. Parker smashes through a window, alerting Luis who is holding Billy hostage. He turns around and shoots Parker in the arm, but leaves himself undefended, and is shot in turn by a member of the infiltration team.
