Can spring 42 1st edition be played with 2nd edition rules?

Is this legal?
Germany attacks Russia: Ukraine to Caucasus and wins.
Germany has left 3 tanks in Ukraine which now blitz through newly conquered Caucasus to hopefully conquer Moscow

Thanks for the help.

During “bridging” can Japan move units from Japan to Manchuria in the same turn?

Can a transport load, move and unload the same unit in one turn?

Where in the rulebook is this clarified?
