I always liked this wall of text by Bunnies. It gives an overview of the first turns for both sides in a KGF kind of game. Perhaps you will find it useful.
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.
No. Your one movement is the loading onto the transport. Any land unit on a transport can be loaded and offloaded on a single turn but it takes up all their movement.
