A round is another word for a bullet that has been fired or is in the weapon. For instance in the army if a soldier asked another how much ammo they have they would say "i have _____ rounds left" or if someone asked you how much you shot someone you would say "they got hit with three rounds" so its just another name for a bullet.
Explosive rounds are FMJ for Light machine guns such as MG4
No. Machine guns are fast and very deadly. They can fire up to 400 to 600 rounds per minute. Some machine guns can fire up to more than 2000 rounds per minute and one machine gun can fire and empty 1 million rounds in one minute. It is called the 1 million rounds per minute gun, one of the fastest machine gun in the world.
There is a broad range of ROF (Rate of Fire). It can be anywhere from a crazy slow 3 rounds per second (some off-brand guns) all the way up to 100 rounds per second (Echo 1 M134). These are the ends of the scale, while most guns fire 10-20 rounds per second on fully automatic.
Every gun in the game and it is not explosive rounds it is FMJ (Full metal jacket)
They used mostly 9 milimetre rounds hand gun or maybe the glock.
The Metal Storm has a cyclic rate of fire of 1.62 million rounds per minute.
The Metal Storm guns have a rate of fire in excess of one million rounds per minute. They cannot hold that many rounds, but they fire so quickly that a burst sounds like a single shot. As in handheld guns it's the KRISS Vector, a SMG that fires 1,500 rounds per minute.
Machine guns can fire more than 1 thousand rounds per minute so yes, they can destroy missiles.
No such thing as a blank gun. You can put blanks in a gun though.
None, a firearm has never killed anyone by itself, People kill people with guns, or they get shot when the gun is not properly cleared of any rounds.
Yes. .50 caliber machine guns weren't invented for war until WWII, but other guns and artillery had large rounds. (bullets)
Its simply (in the case of guns) how many bullets the gun can fire in 60 seconds.
