A Beretta 92FS can be seen in the hands of a police officer who arrests Sam Witwicky (Shia LaBeouf) when he reports his car stolen. Beretta 92FS pistols are also seen as the sidearms of most of the Special Ops soldiers accompanying Captain Lennox (Josh Duhamel). The pistol is likely standing in for the US Army standard issue Beretta M9.
Captain Lennox (Josh Duhamel) can be seen carrying a Para 1911 G.I. Expert pistol as his sidearm in a Serpa-retention holster, and uses it to threaten Agent Simmons (John Turturro) and other Sector 7 agents during the standoff.

Note the skeletonized hammer, extended slide-stop safety, and a beavertail grip safety. (Note that by pushing the 1911 into Simmons' chest, Lennox has unintentionally pushed the slide backwards slightly, out of battery - note the misalignment between the rear of the slide and the top of the frame. This would render the weapon incapable of firing.)
SIG-Sauer P226
Secret Service agents onboard Air Force One can be seen using SIG-Sauer P226 pistols as their sidearms (a factual error: The United States Secret Service never used the P226, only the P228 and P229 in 9mm and recently switched to the .357 SIG because it has more stopping power). The Sheriff at the police station (Rick Gomez) also brandishes a P226 while threatening Sam Witwicky (Shia LaBeouf) during his interrogation.
One of Captain Lennox's men draws what appears to be a SIG-Sauer P228 during the standoff in the Sector 7 headquarters, likely standing in for the US Military issue M11.
Heckler & Koch MP5KA4s are seen being used by Secret Service agents onboard Air Force One, as well as a few Sector 7 agents (notably Brian Stepanek) when meeting the Autobots, who are quickly disarmed of their weapons by Jazz (voice of Darius McCrary).

Heckler & Koch MP5A3
FBI agents are seen armed with Heckler & Koch MP5A3 submachine guns during the raid on Glen's (Anthony Anderson) home, fitted with Surefire 628 dedicated forend weaponlights and Navy trigger groups. Sector 7 agents can also be seen brandishing these in their first meeting with the Autobots, but are promptly disarmed by Jazz's powerful magnet. During the standoff between Captain Lennox's team and Sector Seven at the Hoover Dam, one of Duhamel's men (Brian Shehan) can be seen smacking a Sector 7 soldier in the face with the butt of an MP5A3 fitted with RIS rails, dual mag clamp, and an M68 Aimpoint red dot scope.
Sector 7 soldiers can be seen using Heckler & Koch UMP45s in several scenes during the film, fitted with varying accessories including C-More red-dot sights.
Captain Lennox (Josh Duhamel) can be seen carrying a Colt Model 933 carbine as his weapon of choice in Qatar, distinguishable from the M4A1's carried by his men by the shorter 11.5" barrel. His weapon is fitted with an M68 Aimpoint red dot and AN/PVS-14 night vision scope, a Surefire M900 weaponlight foregrip, Vltor MOD stock, Yankee Hill Manufacturing Phantom Flash Supressor, and an AN/PEQ-2 IR designator (which inaccurately emits the same visible green laser as those on his men's M4A1's).
There are several appearances throughout the early stages of the film of M4A1 Carbines, used by U.S. military personnel at the U.S. Special Operations Command Central (SOCCENT) base during Blackout's attack, as well as by Captain William Lennox (Josh Duhamel)'s Delta team. The M4A1s used by the special forces team are fitted with various SOPMOD accessories including ACOG scopes, AN/PEQ-2 IR designators (which are erroneously shown emitting a laser beam that can be seen by the naked eye instead of the real AN/PEQ-2's invisible Infra-Red laser), RIS foregrips, and camouflage paint schemes.
There are two brief appearances of M16A2 rifles in the film, first in the hands of soldiers responding to Blackout's arrival at the SOCCENT base when he begins his attack, and later in the hands of soldiers guarding Air Force One as Frenzy sneaks off the plane.
When the FBI storms Glen's (Anthony Anderson) home, several agents can be seen armed with Heckler & Koch G36C's fitted with Surefire Universal weaponlights. Sector 7 soldiers can also be seen carrying G36C's, as well as one of Captain Lennox's (Josh Duhamel) men during the standoff at Sector 7 HQ.
During the standoff between Sector Seven and Captain Lennox's (Josh Duhamel) team, one of the Sector 7 soldiers can be seen aiming a SIG SG-552 at Captain Lennox.
A heavily-customized Mossberg 590 (similar to one seen in 2008's Rambo) is used by Agent Simmons (John Turturro) and Maggie Madsen (Rachael Taylor) to fend off Frenzy at the Sector 7 headquarters. The shotgun has a heat shield, Magpul M93A rear stock attached to a Mesa Tactical M4 adapter block, and a Mesa Tactical Top receiver Rail with an EOTech 552 holographic sight.
First Sergeant Donnelly (Zack Ward) and Ranger Team #3 (Brian Shehan) of Cpt. Lennox's (Josh Duhamel) Delta team carry FN M249 Paratrooper SAWs fitted with Leupold CQ/T scopes as their main weapons, primarily during the battle with Scorponok.
Several Browning M2HB heavy machine guns are seen mounted on the roofs of US military Humvees in Qatar when Blackout attacks the SOCCENT base. The Decepticon Brawl can also be seen with a pair of M2HBs atop the turret of his tank form.
When Sector 7 agents capture Bumblebee (voice of Mark Ryan), they use grapple guns mounted on the door of their helicopters. The main build up of the guns is a Browning M2HB machine gun, heavily mocked up with hollywood embellishments.
During the attack on the SOCCENT base in Qatar, FN M240G machine guns can be seen mounted on several Humvees as well as UH-60 Blackhawk helicopters shown searching for survivors following the attack.
During the final battle, several UH-60 Blackhawks sent to airlift Sam Witwicky (Shia LaBeouf) and the All Spark out of Mission City can be seen armed with door-mounted M60 machine guns.
The Decepticon Blackout has an arm-mounted GE M134 Minigun, which he uses to lay suppressing fire on the jeeps at the Qatar base; presumably one of the door guns from his MH-53 alternate mode. Brawl has a similarly mysterious minigun on his arm in robot mode, though it's possible this was his tank mode coaxial weapon.
The Decepticon Starscream (voiced by Charles Adler), being a Lockheed Martin/Boeing F-22A Raptor in vehicle form, has a 20mm M61A2 Vulcan Cannon, which while never used in vehicle form, is used by him to fire from his arm during the final battle in Mission City both to engage real USAF F-22's and the Autobots.
The General Electric GAU-8/A Avenger cannon is seen as the main weapon on the A-10 Warthog ground attack plane that provides air support for the team against Skorponok.
After the Warthogs fail to take down Skorponok, a CGI AC-130U "Spooky" gunship flies over and bombards him with both a Bofors 40mm L/60 and an M102 howitzer.

It should be noted that the Bofors is firing far too fast, as it is reloaded four rounds at a time by human operators. The rate of fire is more consistent with staggered fire from the gunship's 25mm GAU 12/U with occasional shots from the 40mm.
M102 105mm Howitzer
After the Warthogs fail to take down Skorponok, a CGI AC-130U "Spooky" gunship flies over and bombards him with both a Bofors 40mm L/60 and an M102 howitzer.
In addition to the accessories mentioned above, several M4A1's used by Cpt. Lennox's (Josh Duhamel) Delta team are equipped with M203 grenade launchers, most notably Air Force Technical Sergeant Bobby Epps (Tyrese Gibson).
In a behind the scenes featurette, some of the actors participating in military training were given M4A1 Carbines fitted with Cobray CM203 37mm Flare Launchers, standing in for the M203.
Sector 7 soldiers can be seen with early model standalone RM Equipment M203PI grenade launchers while in the Hoover Dam and during the final battle with the Decepticons in the streets of Mission City.

Milkor M32 MGL
Milkor M32 MGL launchers are used by Sector 7 soldiers and Captain Lennox (Josh Duhamel) and his team to battle the Decepticons during the fighting in Mission City, and are fitted with the factory Armson OEG reflex sights. Captain Lennox's M32 is also shown mounting a laser target designator on the side of the barrel. All of the launchers are also fitted with Vltor Modstocks.
In addition to the Milkor M32's, Sector 7 soldiers and some of Captain Lennox's (Josh Duhamel) men can also be seen using Defense Technologies 37mm grenade launchers during the final battle, equipped with folding stocks and C-More red-dot sights.
Another weapon used by Sector 7 soldiers and Captain Lennox's (Josh Duhamel) team during the final battle are several heavily-modified Ramo RT-37 riot control launchers fitted with unknown red dot sights (appears to be a Bushnell Holosight), barrel shrouds and M4 type stocks. Captain Lennox most notably uses one when he charges Blackout on a comandeered motorcycle, skidding underneath the Decepticon to get a clear shot at the robot's weakly-armored lower body. Like the other grenade launchers in this movie, it produces a large muzzle flash which is not remotely possible in real life.
When the cellphone of Glen Whitmann (Anthony Anderson) is used to create a new transformer, the feral robot producing several weapons including a miniature shoulder-mounted RPG-7 launcher.
