Absolutely - particularly the naval units - does anyone know where I can find WWII aircraft carier units for the US and Japanese? I didn't see any under the units but maybe I missed them. It drives me nuts to have modern carriers in 1936! Re Marines, standard Marines are in the game but custom ones would have to be created - not my forte but if someone builds them I can get them in the game. As for the techs, I think they are already there - the unigue units would just need to be added to the appropriate tech.
