Stalingrad Bombing Difficulty...

[SlappyDingle]

Hey fellers...

I'm looking for any advice on how to nail these tiny tanks that are nestled amongst all the trees and houses in the Russian Campaign "Deep Cover(?)" mission? My map shows me 2-3(I can't even tell they're so small) tiny life bars on my map but I don't seem to be hitting the right tanks. The mission times out and I fail every time. Do I have to demolish those specific tanks or does the mission require an overall number of bombed tanks(like 10 or more)?

Thanks...
