United States Army info:

Vehicles:
U.S. Army doctrine puts a premium on mechanized warfare. It fields the highest vehicle-to-soldier ratio in the world as of 2009. The army's most common vehicle is the High Mobility Multipurpose Wheeled Vehicle (HMMWV), commonly called the Humvee, which is capable of serving as a cargo/troop carrier, weapons platform and ambulance, among many other roles. While they operate a wide variety of combat support vehicles, one of the most common types centers on the family of HEMTT vehicles. The M1A2 Abrams is the army's main battle tank, while the M2A3 Bradley is the standard infantry fighting vehicle. Other vehicles include the Stryker, the M113 armored personnel carrier and multiple types of Mine Resistant Ambush Protected (MRAP) vehicles.

Uniforms:
The Army Combat Uniform (ACU) currently features a camouflage pattern known as Operational Camouflage Pattern (OCP). This replaced a pixelated pattern known as Universal Camouflage Pattern (UCP) that proved to be ineffective in many environments.

Weapons:
The army employs various individual weapons to provide light firepower at short ranges. The most common weapons used by the army are the compact variant of the M16 rifle, known as the M4 carbine, as well as the 7.62×51mm variant of the FN SCAR for Army Rangers. The primary sidearm in the U.S. Army is the 9 mm M9 pistol; the M11 pistol is also used. Both handguns are to be replaced by the M17 through the Modular Handgun System program. Soldiers are also equipped with various hand grenades, such as the M67 fragmentation grenade and M18 smoke grenade.
Many units are supplemented with a variety of specialized weapons, including the M249 SAW (Squad Automatic Weapon), to provide suppressive fire at the squad level. Indirect fire is provided by the M320 grenade launcher. The M1014 Joint Service Combat Shotgun or the Mossberg 590 Shotgun are used for door breaching and close-quarters combat. The M14EBR is used by designated marksmen. Snipers use the M107 Long Range Sniper Rifle, the
M2010 Enhanced Sniper Rifle and the M110 Semi-Automatic Sniper Rifle

I bet nobody will read it all.
Anyway enjoy the mod :)
