Weapon Fiddling
By holding in the A button when you have a motar or bazooka you can increase the range and the fire power of the weapon. Also, if you have assault troopers and your gun is constantly becoming over heated try to keep your gun in the sweet spot,spot that enables you to fire the most rounds, just let go of A and hold it repeat and you can lay down more cover fire then an MG nest.
