The game's main weapon, the M4 carbine, has a reflex sight that can be aimed through for zooming in on distant targets.
The weapons are colored a bit differently from their Counter-Strike counterparts, such as the Arctic Warfare Magnum which is now brown instead of green, the Steyr AUG and the Colt M4 carbine are now two-tone police black instead of the usual colors.
This led to several continuity errors, such as a British Army recruitment poster for a Scottish regiment (which would not recruit in England) featuring the word "Honour" being incorrectly spelled in the American English "Honor" and a photograph of a British soldier using an American M4 carbine and urging people to join the "military" (instead of the "army", as a British poster would say).
While only 100 troops were asked, they fought at least a dozen intense engagements in Helmand Province, where the ground is covered in fine powdered sand (called "moon dust" by troops) that can stick to firearms.

The United States Marine Corps has ordered its officers (up to the rank of lieutenant colonel) and Staff Non-commissioned officers to carry the M4 carbine instead of the M9 handgun.
The riflemen employ the M16A4 service rifle, the M4 carbine, the M203 grenade launcher, M249 squad automatic weapon (SAW), as well as the IAR "Infantry Automatic Rifle" the AT-4 and LAW rockets.
Equipment and weapons are introduced, which typically consists of M4 carbines and M16 rifles loaded with Simunition rounds.

Coincidentally, in 2002 the Americans developed a military calibre intended for the M4 version of the M16 family called the 6.8 mm Remington SPC — with similar ballistic properties to the .280 British cartridge — which was intended to provide better ballistics than the 5.56×45mm.
The Colt's Manufacturing Company Advanced Colt Carbine-Monolithic is an improved version of the M4 carbine presented to the United States military at a conference as a possible replacement for the M16 rifle and M4 carbine within the military.
The TA01NSN, a 4x32 ACOG with only tritium night illumination and backup iron sights, is included the Special Operations Peculiar MODification (SOPMOD) kit for the M4A1 carbine used by Special Operations personnel to configure their weapons to individual preferences and mission requirements.
BrickArms makes a variety of minifigure compatible accessories including an M4 carbine, M21 Sniper Rifle, M1 Garand, M84 grenades, M1 Helmet, Stahlhelm, Minigun, AK-47, M3 Grease Gun, M16, and a Combat Shotgun, along with many other items related to warfare.
Colt was the original producer of the M16 rifle, rights to which it purchased from designer ArmaLite, and today offers a complete “Family of Weapons” based around the derivative M4 Carbine, which includes a heavy barreled rifle (HBAR®), a carbine with sliding stock (M4 & ACC-M), a personal defense weapon with folding-collapsible buttstock (SCW), a piston carbine (APC), a Commando® M4 with a 10.5 in.
They include, for example, the Tippmann X7 and the U.S. Army developed Alpha Black (which resemble an M16), RAP4's T68 Paintball Markers (Which resemble the M4 Carbine, has an internal Air or CO2 tank and is magazine fed), or Smart Parts SP8 (based upon the German Heckler and Koch Prototype XM8, and much of the Armotech product line).
More recently, the US Asymmetric Warfare Group purchased the Gas-OperatedHK 416, a M4/M16 type rifle made by Heckler & Koch using the short stroke gas piston system after intensive tests demonstrating the superiority of this system in adverse conditions (dust, sand, intensive use without maintenance)
