About the other stuff regarding the Pacific Campaign I do hope the Japanese get the 'Type 100 Shiki Kikantanju' submachine gun not just the MP18 variant.
wjlaslo-B29's and other heavy bombers were not used in the close tactical support role, they were used as strategic bombers, as in leveling miles of countryside or whatever you wanted to kill. -Only a few M26's were ever in combat, and they were at the very last stages of the war, as in April 1945. -Trains are under consideration and under development. I'd say wait until we know it's possible to implement and then ask about ways to put it ingame. -Bombers? See first note -NEVER ask the think with the N word in it again. It won't happen.
Actually the M26 first saw combat action in Febuary of 1945. It didn't do alot of fighting in WW2 but I would say any Febuary 1945 and on would be a good grounds for having a M26 in the mix.
