Naval Fighter and bomber had a low defense factor.
I only played with Fg A6 D8 C10 or Fg A4 D4 C6, so do you usually play with such low defense factor?
I like both attack of StB or Heavy on AAA.
On Bombers defense, I only think about ground combat, so planes can be hit too.
StB defense seems high, but to me TcB were A6 D6.
I don’t see bombers on defense as being shotdown on airfields.
But rather being used on tactical bombing mission which don’t have clear objectives and targets as on offense.
It is easier to say : to german bombers bomb Stalingrad (while on offence) than bombing soviet units crossing Volga river pretty much everywhere (while on defence).
