Although 'minigun' is often used as a general term, it is actually refering to a particular model. The same with 'vulcan cannon.'
Although machine guns are fully automatic, it is still preferable to fire short bursts instead of spraying aimlessly, as to not waste ammo.
MGs are also refered to as 'Support Guns.' Their main role is to provide cover fire for the other fellow infantry moving from position to position.
