List of equipment of the United States Army

The United States Army uses various equipment in the course of their work.

MRAP vehicles
The Pentagon bought 25,000 MRAP vehicles since 2007 in 25 variants through rapid acquisition with no long-term plans for the platforms. The Army plans to divest 7,456 vehicles and retain 8,585. Of the total number of vehicles the Army is to keep, 5,036 are to be stored, 1,073 are used for training, and the remainder are spread across the active force. The Oshkosh M-ATV will be kept the most at 5,681 vehicles, as it is smaller and lighter than other MRAPs for off-road mobility. The other most retained vehicle will be the Navistar MaxxPro Dash with 2,633 vehicles and 301 Maxxpro ambulances. Other MRAPs such as the Cougar, BAE Caiman, and larger MaxxPros will be disposed.

Modular sleep system
The Modular Sleep System (MSS) is a sleeping bag kit part of the Extended Cold Weather Clothing System (Gen I to Gen III) used by the United States Army and manufactured by Tennier Industries. It consists of a camouflaged, waterproof, breathable bivy cover, a lightweight patrol sleeping bag, and an intermediate cold-weather sleeping bag (note that the color differs depending on the vintage of the gear). Compression sacks are included to store and carry the system. The MSS is available in a variety of camouflage patterns. The patrol bag provides weather protection from 35-50 F. The intermediate bag provides cold weather protection from -5-35 F. Combining the patrol bag and intermediate bags provides extreme cold weather protection in temperatures as low as -30 F. The bivy cover can be used with each of three MSS configurations (patrol, intermediate, or combined) to provide environmental protection from wind and water. The sleeping bags are made of ripstop nylon fabrics and continuous-filament polyester insulation; the camouflage bivy cover is made with waterproof, breathable, coated, or laminated nylon fabric; the compression sacks are made with water-resistant and durable nylon fabrics.

3D printing
In November 2012, the U.S. Army developed a tactical 3D printing capability to manufacture critical components on the battlefield rapidly. Additive manufacturing is now a capability at Rock Island Arsenal where parts can now be manufactured outside a factory including:
 * M1A1 Abrams tank turret
 * 40 mm grenade launcher

Future acquisitions
The U.S. Army has announced plans to replace numerous weapons in its arsenal, such as the M4 Carbine and M2 Bradley IFV.
