F-16 Fighter Jet
Mig 29 Fighter Jet
The enterprises participating in manufacturing of the "MiG" brand products have added a glorious page to the history of the Russian and world aviation. A.I. Mikoyan Design Bureau, founded in December, 1939, included into the RAC "MiG", has elaborated about 450 projects of combat aircraft, from which 170 projects are realized, and 94 - were made in series. In total at domestic aircraft building plants there have been manufactured about 45000 aircraft of "MiG" brand, from which 11000 aircraft have been exported. Over 14000 "MiG" fighters have been produced under licence abroad. "MiG" family brand aircraft protected from aggression the skies of more than 40 countries over the world. Among them there are such glorified fighters as MiG-15, MiG-17, MiG-19, MiG-21, MiG-23, MiG-25, MiG-29, MiG-31.
Machine Guns
The true machine gun is designed for sustained, long-range firepower. Both the SMG and the assault rifle, while highly capable weapons, have significant limitations. They can both fire at a very high rate (usually well over 600 rounds per minute), but neither is actually intended for anything more than a short burst. Their magazine capacities are generally limited to 20 or 30 rounds, and they might even incorporate a special "three-shot burst" setting. A true machine gun, on the other hand, is a heavier weapon than either the sub-machine gun or the assault rifle, it is often belt-fed, and it is intended to fire hundreds or even thousands of rounds in short order. Early machine guns had huge, water-cooled barrels, and later machine guns had smaller air-cooled barrels. Heat was the predominant problem, since the barrel of a machine gun could become red-hot after sustained use. However, advances in materials science eventually permitted the development of light machine gun barrels which could withstand extremely long periods of sustained fire without a barrel change; in one particular test at Fort Benning, Georgia in 1967, an M60 fired a 164 foot long belt of ammunition in a long, single burst! Sparks shot from the barrel with each of the last few hundred rounds, but it delivered the rounds to the target area and it survived the brutal test without serious damage.
Sniper Rifles
The sniper rifle is obviously designed for extreme long-range accuracy. It is usually a single-fire weapon and there are two types of sniper rifle: standard rifles which are "accurized" (eg. picked out during manufacture and testing for unusually high accuracy and/or modified for accuracy) and specialized weapons which have been designed from the ground up for use in the sniper role. These weapons usually have ballistic characteristics similar to those of assault rifles, and the most accurate models can hit man-sized targets from as much as 800 metres away. It should come as no surprise that sniper rifles are usually equipped with sophisticated targeting devices such as telescopic sights, rangefinders, light-amplification scopes, etc. Some sniper rifles are also capable of fully automatic fire, based on the rationale that if a sniper is detected, he may need to defend himself with more firepower than a single-shot weapon can provide. However, snipers look rather unfavourably upon these dual-purpose weapons. The operating mechanism of an assault rifle is rather different than that of a purpose-built sniper rifle, and automatic fire will tend to throw components out of alignment. Therefore, a dual-purpose weapon sacrifices accuracy in the name of firepower, and since snipers generally work in pairs anyway, this trade-off is unnecessary because the other man will always have a proper support weapon ready.
Assault Rifles
The assault rifle is a handheld long gun which can be either semi-automatic or fully automatic, and which is designed for medium-range firepower. Its long, rifled barrel and solid stock give it superior accuracy when compared to the SMG, the carbine, or the handgun; for example, the C7 (the Canadian designation for the M-16) has a specified effective range of 400-500 metres, although such ranges are probably academic under realistic combat conditions (and it should be noted that on the firing range, their useful range is said to be more like 200 metres).
Carbines
Since SMGs are generally designed to fire low-velocity 9mm or .45" calibre pistol rounds, there are limits to their performance, particularly with respect to armour penetration. If someone requires a weapon with greater effective range or penetration, there is an alternative: the carbine. A carbine is distinguished from an SMG primarily by its use of a rifle cartridge (it is basically a rifle with a shortened barrel), and there can also be differences in operating mechanism. The principal SMG attributes of low cost, good short-range firepower, and midrange accuracy are valuable, but against a target wearing body armour, a carbine provides many of the same attributes while also providing the benefits of the high-velocity rifle cartridge.
