_mofo Do you know your weapons

Episode 4 by AZsithlord_mofo
blatantly copied from

"Ah the Machine gun, force multiplier, a weapon that can turn one soldier into a squad can suppress the enemy from distance in order for his comrades to advance.
My experience with the military was colored wonderfully by the M60, a monster of a weapon by today's standard. I learned by being the team gunner (we had 3-4 per squad in the MP corps) that this monster could be used from simple suppression to the more complex clearing of buildings (within and without) from full-auto glory to a single shot killer. Good teachers and practice could make it unbelievably accurate, and a good steady position could control an area without equal.
Ah how i miss the "Hog" and the 27 pounds of weapon it was, not counting the 200 to 600 rounds usually on my assistant gunner and myself. (yeah, 1200 rounds of wreckage).
my experience was limited but enjoyable with the M249 SAW. it burned through ammo far to quickly for my tastes, but then you got to carry twice as much when fielding it"

Machine guns

Old Maxim MG on heavy artillery-style mount
First machine gun was invented in USA by Hiram Maxim in 1883 and patented two years later. First wars Maxims' MGs was taken into was colonial war in South Africa and Russia-Japan war (1904-1905). During WW 1 all sides used many machineguns, both heavy (on wheels or tripods) and ligth (on bipods). After WW1 MGs become a standart issue as a squad weapons for ground and anti-aircraft warfare. Most widely used MGs were Maxims (in many modifications), Brownings M1919, Gotchkiss. Between two World Wars first appeared large caliber MGs (as a rule, its caliber was .50", or 12.7mm). Best examples - Belgian/American Browning M2 and Soviet DShK-12.7. During WW2 Germans developed first mass "universal" MG (Mg42, later - Mg43), which can be used as a "ligth" MG on bipod or as a "heavy" one on tripod against ground or air targets. This MGs set the trend, so almost all modern "medium" MGs such as Belgian MAG, American M60, Russian PKM may be used on bipod or tripod, as needed.
Today the main role of all MGs is to provide sustained firepower for troops against enemy troops and unarmored targets. Heavy (.50/12.7mm) MGs can deal with lightly armored targets such as APCs, recon vehicles, helicopters.
Almost every infantry squad in the world has at least one light MG. Russian squad usually equipped with one RPK-74 MG, US Army squad - with two M249 SAWs. Medium MGs usually are installed on vehicles (APCs, Jeeps, tanks) and used in infantry on ground mounts on troop and company level. Heavy MG are sometimes used as anti-aircraft weapons on tanks, main weapons on APCs and recon veichles and company level support weapons in infantry.
Almost all heavy and medium MGs, and many light ones, have quick interchangeable barrels. Usually every MG comes from factory with one or two spare barrels, wich may be changed in battle environment within seconds. This feature provides ability to sustain intensive fire for longer time while one barrel is being used, the spare one can be cooled - intensive heating during the fire can dramatically decrease accuracy and reduce the lifetime of the barrel.
belt feed heavy .50 cal MG in ready-to-fire position

The feeding systen of almost all medium and heavy MGs is build around belted (or linked) ammunition. Early belts were made from textile, modern belts are made from metal. Metal belts may be "disintegrated" or non-disintegrated.
desintegrated 7.62mm metal belt
In the disintegrated belt the metal links are linked ty each other by the cartridge. When feeding system of the MG removes cartridge to feed the MG, links fall apart, thus "disintegrate" the single belt into the links. In non-disintegrated belts links are connected by the means of special details, and belts remains "one piece" even when all cartridges are removed. Usual belt capacity for heavy MG is 50-100 rds, for medium and light ones - 100-250 rds.
Beta-C 100 rounds 5.56mm NATO magazine

Light MG often employs the magazine feeding system, using the standard 'assault-rifle' style box magazines for 30-45 rounds each or hi-capacity drum or dual drum (Beta-C and others) magazines for 50-100 rounds each. In light MGs, made from assault rifles, magazines usually exchangeable between LMG and assault rifle. Good examples are AK and RPK Russian, Steyr AUG Austrian and L85/L86 British systems. Some light MGs such as FN Minimi/M249 are dual-feed and can use belts or box magazines without any modifications.
