Who ya gonna call?

You’re an infantry captain, and your company is holed up in a defensive position inside a group of bombed-out buildings. A numerically overwhelming force, say brigade strength, of mechanized infantry backed up with tanks, is bearing down on you. You call in air support to cover your withdrawal, and help is on the way.

What do you hope is coming? Fixed wing? If so, what? Rotary wing? Again, if so, what? Obviously, for the sake of argument, assume anything and everything could be coming.
