I've been DHing like crazy on LG's I should totally overrun.

This last one had:
Turrets 120,433
Tanks 11,758
0% def bonus
no weapons

so at most thats what, 143,949 turrets worth, plus at most 2 def allies= 215,923 def power.

I sent 275,000 Jets and lost. WTF? I've bounced a shiet load of LG's here, how much do you have to oversend?

Go read the wiki again. Your allies can double your defensive strength.

Yeah obviously I remembered incorrectly how the calc worked.
