cc Guppy I was using that photo just to illustrate that there were cannon armed US A-20's in combat.
Don't think anyone has disputed that. It was pointed out that the A-20s that used the 20mm cannon package did so during operational combat field testing and didn't see widespread use. ack-ack
Cannon armed A-20's saw combat in the South Pacific with US squadrons. Yes they were not favored, due to the 20mm's performance in real life, but that hasn't stopped other aircraft in AH being highly used.(Image removed from quote.)
