CM is a game about combined arms. There weren't much of any on that front really.
If you want to play it, make the Commonwealth forces Japanese - strip out the mortars, the Fireflies, the rapid artillery, the Bren Carriers...the airforce, the 6pdrs the Crocodile, the Vickers...anything other than the Lee-Enfield really.
Ratchet the fanaticism up to 11 and you're ready to rock.
