Brazil (US) and Madagascar (UK) are allied territories.
The Axis can capture them by unloading transports in their combat move.
The Allies can place units there by unloading transports in their noncombat move and/or by landing planes.
To me, it seems that the miniatures in AA42 have a better finishing. In my AA50 the miniatures are not so good. Russian an Japanese fighters are bend, ships of alla navies have molding problems. Maybe refreshed is intended in the sense they have re-modeled the “original” of each miniature.
I sent WOTC an email about my bent planes, ships, etc. They replaced all of them for me. I recommend the same. Check the box for the web site and go to customer service (not near my box at the moment).
