Ah ok, thank you both very much for your help.  We were confused as to how to operate the two and were operating them in seperate phases.  We had decided that when the units would cross the line under persia onto the pacific map, that they would turn into British Pacific units.  Thanks again for the clarification on that, we were so confused

What is the ruling on mixing the European British and the Pacific British units?  When one crosses into the other side of the board, does it change hands?
