Are jets sent on PS protected from bomb airbases? I often seem to get very low returns on ops.

yep and same with troops.

also if your jets are on PS, your results are de minimis

Hmm. Even when they're on both sidesback it's rubbish. Is it a DR thing?

you gotta wait a full tick after they come back sometimes otherwise they will have a negative counter on them.

if you have 1m jets they have 1m jets you will take out the max

spy dr has no dr other then increased spal for the target.

what that n00bprince said, you need alot jets or troops if you are trying to get rid off opponent's jets/troops and same applies to bomb bankings etc.
