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 Ranger team. The M4A1's 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 camougflage paint schemes.
In addition to the accessories mentioned above, several M4A1's used by Cpt. Lennox's (Josh Duhamel) Ranger team are equipped with M203 grenade launchers, most notably Air Force Technical Sergeant Bobby Epps (Tyrese Gibson).
We also see Sector 7 soldiers wielding stand-alone M203 grenade launchers while in the Hoover Dam and during the final battle with the Decepticons in the streets of Washington D.C.
Captain Lennox 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 10.5" barrel. His weapon is fitted with an M68 Aimpoint red dot and AN/PVS-17 night vision scope, a Surefire M900 weaponlight foregrip, Command Arms Accessories ARS stock, custom "Vortex" style muzzle brake, and an AN/PEQ-2 IR designator (which inaccurately emits the same visible green laser as those on his mens' M4A1's).
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.
A heavily-customized Mossberg 590 (similar to that seen in Rambo (2008)) is used by Agent Reggie Simmons (John Turturro) and Maggie Madsen (Rachael Taylor) to fend off Frenzy at the Sector 7 headquarters. It has a 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.
Milkor M32 MGL launchers are used by Sector 7 soldiers and Captain Lennox (John Duhamel) and his team to battle the Decepticons during the fighting in Washington D.C., 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.
Captain Lennox (Josh Duhamel) can be seen carrying a customized M1911A1 pistol as his sidearm in a Serpa-retention holster, using it to threaten Agent Simmons (John Turturro) and other Sector 7 agents during the standoff.
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.
First Sergeant Donnelly (Zack Ward) and Ranger Team #3 (Brian Sheehan) of Cpt. Lennox's (Josh Duhamel) Ranger team carry FN M249 Paratrooper SAWs fitted with Leupold CQ/T scopes as their main weapons, primarily during the battle with Scorponok.
Sector Seven soldiers can be seen using Heckler & Koch UMP's in several scenes during the film, fitted with vaying accessories including C-More red dot sights.
Another weapon used by Sector Seven soldiers and Captain Lennox's team during the final battle are several heavily-modified Brügger & Thomet GL-06 grenade launchers, covered in Hollywood embellishments and fitted with an unknown red dot sight (appeares to be a Bushnell Holosight). 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.
While at Sector Seven HQ, the power of the Allspark is demonstrated when Glen Whitmann (Anthony Anderson)'s cellphone is used to create a new transformer, the feral robot producing several weapons including a shoulder-mounted RPG-7 launcher.
In addition to the RPG-7 mentioned above, the feral transformer created from Glen's cellphone is also armed with a GE M134 Minigun, mounted underneath its' body.
Secret Service agents onboard Air Force One can be seen using SIG-Sauer P226 pistols as their sidearms (a factual error: the Secret Service never used the P226, only the P228 and P229) This was also done in Air Force One. A cop at the police station (Rick Gomez) also brandishes a P226 while threatening Sam Witwicky (Shia LaBeouf) during his interrogation.
The Heckler & Koch MP5K can be seen being used by Secret Service agents onboard Air Force One, as well as by a Sector Seven agent (Brian Stepanek) when meeting the Autobots, the latter being disarmed of his weapon by Jazz.
Sector Seven agents can be seen brandishing Heckler & Koch MP5A5's in their first meeting with the Autobots, but are promptly disarmed by Jazz. FBI agents can also be seen carrying them during the raid on Glen's home, fitted with Surefire dedicated forend weaponlights.
When the FBI storms Glen's home, several agents can be seen armed with Heckler & Koch G36C's fitted with tactical flashlights. Sector Seven soldiers can also be seen carrying G36C's, as well as one of Captain Lennox's men during the standoff at Sector Seven HQ.
Several Browning M2HB heavy machine guns were seen mounted on the roofs of US military Humvees in Qatar when Blackout attacked the SOCCENT base. The Decepticon Brawl can also be seen with a pair of M2HB's atop the turret of his tank form.
During the attack on the SOCCENT base in Qatar, 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 and the Allspark out of Mission City can be seen armed with door-mounted M60D machine guns.
Brawl's tank form is an extremely large prop rather than a real tank, and was originally built for the movie XXX 2: State of the Union; it was modified for Transformers to carry a replica of the "Venus Fly Trap" MCBS [minus the two forks and "dog bone" magnetic mine detonator] and a pair of quad missile launch tubes on the secondary turret. The hull is a modified truck chassis with the rear shortened and the radiator cut off, using a Freightliner diesel engine and rubber band tracks taken from a construction vehicle; it is noticably too light for a real Abrams, as can be seen from how high it rides up as it runs over a car in Mission City. In addition, extras in the Mission City sequence don't seem to have been advised that they should be avoiding a 40-foot area surrounding the tank's turbine exhaust; some are standing in positions where they'd be severely burned if the tank was real.
The main gun is secured using a non-functional travel lock that has a tendency to disappear and reappear between shots, most likely there to stop the top-heavy prop turret falling off the chassis during the car-crushing sequence, as it has no visible hinge to fold down and is not a component of either the Abrams or the Leopard 2, the two tanks the prop is based on. Indeed, the turret visibly wobbles during this sequence. The main gun noticably doesn't recoil; barely at all in one shot of the muzzle, and not at all in another; by comparison, when the CGI version of the tank fires shortly afterwards the gun recoils as would be expected.
