Machine gun or machinegun. All of them are automatic, so it is redundant to say that. There is no such thing as a semi automatic machine gun, or a single shot machine gun. That answer is correct, but many people use the term fully automatic machine gun or full auto machine gun to specify they are not talking about a semi-auto pistol or rifle, which are commonly referred to as autos, and sometimes that term confuses people.

There really isn't a "traditional" word for it. It could be a machine gun section, machine gun squad, machine gun platoon, machine gun company, a group or cluster of machine guns, etc.
