What's minimum size bomb for taking out GV's?
I use 1000 pounders (because I can). 500's also work well. I've never tried with 250's but the smaller the bomb gets the more accurate your drop has to be (lower blast radius). I can also kill a panzer or flak with rockets set to salvo 3 with .05 delay from a F6F-5 using the same technique as in dropping bombs.
