Just FYI for anyone interested in knowing. If you want to speed up the process of destroying a tiger tank and its AA guns that's usually accompanied with it, all I do is use a lvl5 transport plane to go in first to take the shots fired bye the AA then directly behind it is my 10 bombers that target the tiger and splash from bombs destroy the AAs. I take minimum damage to transport and return to base and heal it. U can use less bomber but no less than 8.
