I know. I've had all gun emplacements aimed accordingly.
sir! the radar! the bugs are screaming out of the east!
what? impossible!
sir! look! there's thousands of 'em!
shit, they have big wings.
the guns! they're pointed the wrong way!
call in air mobile. on the double.
yes, sir!
and get me a gun. a great big gun.
