Use the old Red Japanese A&AP Infantry for that - or potentially the old Yellow Japanese Infantry from A&A 2nd Edition.
Sounds like a good idea - care to post the full rule?
New South Wales have an value of 2 IPC and a major IC. This is a special rule. I think the game would have been better off if NSW had an value of 3PC, and fit into the mainstream rules. It was not neccesary to have Victoria territory with 1 IPC. Who the f’‘’* will ever attack Victoria ?
The Antarticans
…or maybe neutral Sweden ?
