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.
