Yes and no. Some machine guns are heavy and some are not. It depends on which type of machine gun.
Yes. All Gatling guns are heavy but have to be hand cranked and fed bullets at the same time. Machine guns are also heavy too but not all of them. Machine guns have to fed bullets only but machine guns also spray more bullets much faster than Gatling guns.
There are always exceptions, but, as a general rule, NO.
they used heavy duty machine guns
The weapons that were used in Kokoda were rifles, revolvers and Lewis Machine guns by the Australians and Heavy machine guns, mortars and mountain guns by the Japanese
In World War 2 there were three types of machine guns used: squad support weapon, medium machine gun, and Heavy Machine gun such as the Browning M2, and the M1919
Yes because machine guns are much better than gatling guns. With Gatling guns, you have to crank and put bullets in at the same time so they can open fire but with machine guns, you don't have to crank them. Just put in bullets, place them on the ground and let them activate. If you have Gatling guns, you have to carry them and hold them but they are very heavy and also not fully automatic. With machine guns, you do not have to carry them and hold to let them open fire. Some machine guns are heavy and light but they open fire automatically without having someone to crank but even though, machine guns are faster and much stronger than Gatling guns. They can fire up to thousand to 1 million rounds per minute while Gatling guns can fire up to 60 rounds per minute. Winner: Machine guns have beaten Gatling guns.
Which aircraft? In WWII armament ranged from zero (trainers, etc) to rifle-calibre machine guns, heavy machine guns, cannons (15 mm upwards), heavy guns (57 mm, 75 mm, 105 mm), rockets, torpedoes, bombs, mines...
They were very heavy and cumbersome, making them difficult to transport. Additionally, they were water cooled, meaning a supply of water for the machine guns had to be kept on hand.
There were several different types of machine guns in use. Most fell into the "medium" category, and had a bore typically ranging from 6.5 to 7.92mm. The heavy machine guns tended to have a bore in the vicinity of 12.7mm, but also includes the 14.5mm KPV machine gun. 20mm and larger are considered cannons.
No. Machine guns will beat Gatling guns.
Machine guns.
