What technical advances did the machine gun make during world war 2?

Answer 1

US designer, John Moses Browning, designed the current .50 caliber machine gun, as well as the .30 caliber m.g. in WW1 (1917). Those m.g.'s were used in WW2. The only new types of m.g.'s were the submachine guns that were developed in the 1920's (Thompson's .45 submachine-gun), and the M-3 Grease Gun. Sub machine guns fired PISTOL ammo. The US used the same machine guns in WW1 (foreign machine guns as well as Browning's weapons), WW2, and the Korean War (which used WW2 equipment since there was only a 5 year time gap between the two wars). The Vietnam War saw the US Army's first use of new machine guns, such as the M-60 machine gun and the M-16 Assault Rifle, which was the ONE and ONLY time that the average US Rifleman (Grunt) was armed with a fully automatic rifle for general issue (standard issue). After the Viet War, the M-16's were converted to short round bursts (no more rock 'n roll-fully automatic fire).

Answer 2

Lighter, man portable machine guns were developed in order to accommodate the 'walking fire' tactic and to allow the firepower of a machine gun to be transported with the troops crossing no man's land.

Answer 3

Machine guns were introduced in WWI (World War 1) 30 years before WWII (World War II). As such they did not really change anything. When they were introduced in WWI they completely changed warfare, but by WWII machine guns were actually a standard weapon, nothing new or special.

The new technologies developed in WWII were Jet Engines, Rockets (Both Artillery Rockets and Bazookas), Atomic Weapons (Nukes), Assault Rifles, and enourmous leaps in Tank and Aircraft technology (from biplanes to jetfighters and from 5 ton armoued tractors to 200 ton super-tanks (Pz VIII Maus))
