IMO it shouldn't have formations. It wasn't a 1000-plane-mission type of bird. It was small missions, pinpoint precision. None of this carpet bombing stuff. And it never flew in box formations to cover other bombers with its guns (because... hah! It has none...)
Overall I'd like to see it like the B5N or TBM or B-25H: No drones.
it the Mk B XVI was not a pinpoint precision bomber....... it carried the cookie and dropped it from considerable altitude with all the (in) accuracy that involves. It flew missions in squadron strength against significant strategic targets.
the fighter bomber we have now did fly many intruder raids very often just as a pair some times even solitary raids (particularly into Southern France and Northern Italy from Sicily or Southern Italy) It was far more "precision" in its role. It was essentially an attack aircraft.
My view is that it (Mk B XVI) should be formation enabled and perked appropriately. It does not have to have been a participator in mass bombing raids to qualify for this IMO.
My biggest concern is its (Miss) use in AH against GV's. One way to fight this would be to make it perked and ONLY available in formations when carrying the cookie (or simply perk the cookie).
