transfer eastern front to western front and vice versa

[caelarius]

ok. i dont know, if that here is the right forum for my problem. i try so.

for more than 20 years ive been playing eastern or west front (talon soft...now campaign series). with a big break
within.
and there is one question: why is it not possible to transfer units from
eastern or west front to rising sun? for example, Germans against Russians in
Japan? or japanese troops in germany? or is there a chance to do so?

or why is there no ...bundle to mix all the unit and to use all the maps?

maybe i get an answr. tax for that
