American Firearms Used to Combat the Global War on Terror

The attacks on the World Trade Center, the Pentagon, and four hijacked commercial passenger planes on Sept. 11, 2001, are the events that propelled the United States to begin its campaign against the Global War on Terrorism. Then-president George W. Bush cautioned that this conflict would not end until terrorism was wiped out. American soldiers outfitted with some of the best arms, aircraft, and vehicles descended on the Middle East for the next two decades, aiming to quell terrorist activities in the region.

Some of the most valuable assets deployed were aircraft, naval vessels, and armored vehicles although it was the infantry troops that were ultimately the ones to maintain order. These troops were outfitted with a series of American-made guns — sniper rifles, shotguns, battle rifles, and more — some with service lives dating back more than half a century. (These are the 50 most popular guns of all time.)

24/7 Wall St. reviewed multiple catalogs of modern American firearms from Military Factory, an online database of arms, vehicles, and aircraft used in militaries worldwide to identify the American firearms used to combat the Global War on Terror. We ordered these weapons alphabetically and included supplemental information from Military Factory regarding the type of weapon, year introduced, manufacturer, maximum effective range, and caliber of each weapon.

The Remington M2010 Enhanced Sniper Rifle was introduced to service in 2011 as a standard tactical sniper rifle. It is a modern iteration of the Remington Model 700, which was renowned for its accuracy and consistency. The M2010 ESR is chambered for the Winchester 300 magnum round with a 5-round magazine, comes standard with the Leupold Mk IV tactical scope, and has a maximum effective range of 3,935 ft. (These are the classic long-range sniper rifles of World War II.)

In addition to sniper rifles, which were not the only guns issued to troops during this conflict, shotguns like the Mossberg Model 590 or carbines like the Colt M4 became standard issue, as did sidearms like the Colt M1911. All of these firearms and more added to the combat effectiveness of U.S. troops when they fought the Global War on Terror.
