The M4 carbine is a family of firearms tracing its lineage back to earlier carbine versions of the M16, all based on the original AR-15 designed by Eugene Stoner and made by ArmaLite. It is a shorter and lighter version of the M16A2 assault rifle, with 80% parts commonality.
It is a gas-operated, air-cooled, magazine-fed, selective fire, shoulder-fired weapon with a telescoping stock. A shortened variant of the M16A2 rifle, the M4 has a 14.5 in (370 mm) barrel, allowing the individual soldier to better operate in close quarters. The M4 has selective fire options including semi-automatic and three-round burst (like the M16A2), while the M4A1 has the capability to fire fully automatic instead of three-round burst. The carbine is also capable of mounting an M203 grenade launcher, the M203A1 with a 9-inch barrel as opposed to the standard 12-inch barrel of the M203 used on the M16 series.
The M4 carbine is slated to eventually replace the M16 rifle for most combat units in the United States Army. The winner of the Individual Carbine competition may replace the M4 carbine in U.S. Army service.
ammunition
The M4 and its variants fire 5.56x45mm NATO ammunition (and .223 Remington ammunition) and are gas-operated, air-cooled, magazine-fed, selective fire firearms.
advantages
As with many carbines, the M4 is handy and more convenient to carry than a full-length rifle. The price is slightly inferior ballistic performance compared to the full-size M16, with its nearly 6" (15 cm) longer barrel. This becomes most apparent at ranges of 300 yards and beyond. Statistically, however, most small-arms engagements occur within 100 yards. This means that the M4 is very much an adequate weapon for the majority of troops. The marginal sacrifice in terminal ballistics and range, in exchange for greatly improved handling characteristics, is usually thought to be a worthwhile compromise.
While the M4's maneuverability makes it a candidate for non-infantry troops (vehicle crews, clerks and staff officers), it also makes it ideal for close quarters battle (CQB). The M4 was developed and produced for the United States government by Colt Firearms, which had an exclusive contract to produce the M4 family of weapons through 2009.
however, a number of other manufacturers offer M4-like firearms. The M4, along with the M16A4, have mostly replaced the M16A2 in the Army and Marines. The U.S. Air Force, for example, has transitioned completely to the M4 for Security Forces squadrons, while other armed personnel retain the M16A2. The US Navy uses M4A1s for Special Operations and by vehicle crews.
Some features of the M4 and M4A1 compared to a full-length M16-series rifle include:
Compact size
Shortened barrel 14.5 in (370 mm)
Telescoping buttstock
However, there have been some criticisms of the carbine, such as lower muzzle velocities and louder report due to the shorter barrel, additional stress on parts because of the shorter gas system, and a tendency to overheat faster than the M16A2.

Squad Automatic Wepon (SAW)
A squad automatic weapon (SAW, also known as section automatic weapon or light support weapon) is a weapon used to give infantry squads or sections a portable source of automatic firepower. Weapons used in this role are typically either light machine guns or selective-fire rifles, usually fitted with a bipod and heavier barrel. SAWs usually fire the same cartridge as the assault rifles or battle rifles carried by other members of the unit. This reduces logistical requirements by making it necessary to supply only one type of ammunition to a unit.
Length: 4 ft
Weight: 5 kilograms
recoil force: 4 pounds
attachments: bipod, holographic sight, red dot sight etc
bullets: .45 caliber standard assult rifle 12 milimeter rounds. multiple types such as tracers, incendiary and many more.

M61-vulcan minigun
The M61 Vulcan is a hydraulically or pneumatically driven, six-barreled, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm rounds at an extremely high rate.The Vulcan is a Gatling gun: each of the cannon's six barrels fires once in turn during each revolution of the barrel cluster. The multiple barrels provide both a very high rate of fire—around 100 rounds per second—and contribute to long weapon life by minimizing barrel erosion and heat generation. Mean time between jams or failures is in excess of 10,000 rounds, making it an extremely reliable weapon.A variety of Armor-Piercing Incendiary (API), High Explosive Incendiary (HEI), and training rounds are available.
m240 machine gun
The M240, officially Machine Gun, 7.62mm, M240, is the US military designation for the FN MAG (Mitrailleuse d`Appui Général, "General Purpose Machine Gun"), a family of belt-fed, gas-operated medium machine guns firing the 7.62x51mm NATO cartridge.[1]
The M240 has been used by the United States Armed Forces since the mid-1980s. It is used extensively by infantry, as well as ground vehicles, watercraft, and aircraft. Despite not being the lightest medium machine gun in service, it is highly regarded for reliability, and its standardization among NATO members is also seen as a major advantage.
All variants are fed from disintegrating belts, and are capable of firing most types of 7.62 mm NATO ammunition. M240 variants can use non-disintegrating belts (following replacement of a few easily-swappable parts). There are significant differences in weight and some features among some versions which restrict interchangeability of parts. The M240s used by the US military are currently manufactured by FN Manufacturing, a US-based branch of FN Herstal.The M240B and M240Gare usually fired from an integrated bipod, the M192 tripod, or a vehicular mount.

Ultimax machine gun.
this Singapore manufactured gun fires similar rounds to the m4 carbine(m4a1). this gun can be loaded with a 30 round magazine or a 120 round drum. this weapon has very low recoil and can be be fired by a child due to the spring system that absorbs the recoil after every shot.
desert eagle .50 caliber AE
This weapon is the worlds second most powerful handgun after the smith & welsons 44 magnum. this gun can fire 10mm .50 caliber ammunition.the type of ammunition can vary depending on what you load(tracers, hallow point etc.). this wepon is used in several countries such as the United States, Israel and many others.
