As the townspeople hole up in the grocery store they discover something bad is out in the mist. In search of weaponry, Amanda Dumfires (Laurie Holden) reveals a sidearm she keeps in her purse. This sidearm is a Colt Magnum Carry, the stainless reproduction of the Colt Detective Special chambered in .357 Magnum. Unfortunately for the group, she only carries two speed loaders for it. In search of someone with enough experiance to use the gun, Ollie Weeks (Toby Jones) steps up, claiming he was a competition shooter in the '80s. The gun is used several more times before Ollie is killed by a creature in the mist as he follows the group of surviving protagonists out to the car in an attempt to escape. The gun falls into the hands of David Dreyton (Thomas Jane), now only loaded with four bullets. The group of five drives their car out as far as possible before running out of gas. To spare the group the deaths awaiting them out in the mist, David offers to kill them with the gun and figure something out for himself. He then kills everyone in the car and steps outside so the creatures of the mist can take him, only for the U.S. Military to arrive and rescue him.
M4A1 Carbine
The U.S. Military personel sweeping the mist away are armed with M4A1 carbines at the end of the film, fitted with RIS foregrips, C-More red dot sights, Surefire universal weaponlights, ACOG scopes, and AN/PEQ-2 IR designators.
M203 Grenade Launcher
One of the U.S. Military personel's M4A1 is fitted with an M203 grenade launcher. It could also be a Cobray 37mm Launcher but it isn't seen close enough to be sure.
FN M240D Machine Gun
Mounted on top of the U.S Military tanks and self-propelled artillery vehicles are FN M240D machine guns, since the spade gripped model is more commonly mounted on tanks and the users appear to be holding spades.
