Baumer, you are the one twisting things here... Field mods at a depot level aren't field mods. Did you know that B-29s had to undergo over 50 "modifications" after leaving factories before they were even allowed to be distributed to squadrons? These are not "field mods." They are systematic changes done at a level above some average Joe in a squadron taking things into his own hands. Field mods are akin to P-38s carrying 6x50cal, or IL2s that had the aft fuselage carved out and a gunner stuck there when none was supposed to be there.
Wmaker, key words there are H-6. For an H-3 yes a MG/FF in the nose was a field mod. If they have given us an He-111 with torpedoes and an He-111 with a nose 20mm MG/FF gun, has anybody checked the specs on the engine power? It seems like they gave us a version very much post-dating the BOB which it was intended for in the first place. Given that the bombload includes a large selection of over-sized bombs up to and including the 1600kg, it seems like all the indicators point to a post-BOB H-6 model that shouldn't ever be used in the BOB scenario.
Now that I think about it, the fuel tanks in the bomb bays are signature of the H-5 and H-6 models. First introduced in the H-4, which was a short run leading up to the H-5 and mostly didn't see service in the BOB. It also had engines with between 140-200hp more (per engine) than the H-3 carried.
It seems HTC gave us an entirely inappropriate model for the BOB.
