Raza's Ten Rings fighters carry Heckler & Koch G36K assault rifles, most fitted with G36C-style carry handles. In the film, Tony Stark (Robert Downey Jr.) learns that Obadiah Stane (Jeff Bridges) had been secretly selling Stark Industries weapons behind his back to the Ten Rings as part of Stane's attempts to take over Stark Industries, making them better armed than any of the other militant factions in Afghanistan and Pakistan. The various assault weapons used by Raza's men, including the H&Ks, are therefore supposed to be Stark Industries products. It is also possible that in the Marvel universe, Stark Industries obtained a license from Heckler & Koch to produce G36 and UMP-series weapons in the U.S. Or that Stark industries has bought Heckler & Koch.

Heckler & Koch G36C
Several of Raza's men are also armed with the compact version of the G36, the Heckler & Koch G36C. The G36's are also outfitted with many accessories to disguise their origins. During the escape from the Ten Rings' camp, Yinsen (Shaun Toub) grabs a G36C dropped by one of the fighters and runs towards Raza's men firing wildly, trying to divert attention from Stark until the suit is powered up and he can use it to fight his way out.
Raza (Faran Tahir) is seen with a H&K G36K fitted with a Heckler & Koch AG36 grenade launcher, which he fires at Stark in the prototype Iron Man armor, but misses and is knocked out by Stark's missile instead.
Several of Raza's men are armed with the .45-caliber version of the Heckler & Koch UMP with tactical outfitting.

This is a Screen used UMP-45 outfitted with a C-More sight and Surefire Tactical light grip as used on the film Iron Man (2008).Error creating thumbnail: File missingHeckler & Koch UMP45 - .45 ACP. This is a closeup of the custom markings on a Screen used UMP-45. All of the weapons purportedly to be from Stark Industries were indeed set up with "Stark Industries" Markings. What is interesting here is that the Stark Industries plate says that it is a 5.56mm weapon, when the plate is affixed to a UMP-45 (.45 ACP) submachine gun. The plates are probably generic props that were affixed to all "Stark" weapons since most of the customized weapons were M4s and G36s.Error creating thumbnail: File missingCarrying an assortment of rifles, these terrorists are seen holding UMP 45s.Error creating thumbnail: File missingTerrorists fire UMP 45s as well as some H&K G36K rifles.
SIG SG 552
One of Raza's men is seen armed with a SIG SG 552 with tactical outfitting.
USAF Airmen stationed in Afghanistan are seen armed with M4A1 carbines. They are also used by airport security when Tony Stark returns to the United States. The M4A1's in the movie are equipped with Insight Technologies ISM-V scopes; These scopes have built-in laser aiming modules and night-vision, thus eliminating the need for anything but the handgrip.
Held by one of Raza's men is an M4A1 with a Magpul Buttstock and an M26 Modular Accessory Shotgun System (MASS) fitted under the barrel. While the carbine's grip appear to be removed, close inspection reveals his sleeve is in the way.
Trivia: The image in question is a heavily edited clip that is included on the U.S. version of the trailer. The M4 with M26 is put in to replace another shot of the weapon that is pointed at Tony Starks' head. The MPAA doesn't allow trailers to show any weapons to pointed at a person, even if that's how the final cut shows it. The same thing happened in the trailer for Indiana Jones and the Kingdom of the Crystal Skull
Both Ten Rings fighters and USAF Airmen in Afghanistan can be seen using the Browning M2HB 50-caliber machine gun. The Ten Rings fighters place the machine guns in their camp, with the USAF Airmen have them mounted on top of their Humvees.
One of the Ten Rings members attempts to shoot Stark in the head with a Heckler & Koch USP when his arm gets stuck in the wall, but the round deflects off the armor and hits him instead. Abu Bakaar (Sayed Badreya), the leader of the Ten Rings guerrillas is also seen with a USP at his hip in a holster.
The SHIELD agents escorting Pepper Potts (Gwyneth Paltrow) to arrest Obadiah Stane (Jeff Bridges) are armed with Glock 17 pistols, which they fire at Stane, now "Iron Monger", but prove useless and they are easily dispatched.
In the ending credits there's a drawing of character, that will appear only in Iron Man 2 -War Machine with M134 Minigun mounted on the shoulder of his armor.
