Assuming you are talking about a no bid game:
Purchase: 8 infantry, submarine.
Attacks:
Africa- blitz FEA with tank from Libya and move it to Algeria. Take FWA with infantry unit from Algeria.
Take out caucauses if at all possible with ground units only(Russia usually only leaves one or two infantry there). I’ll usually attack one infanty with one infantry and a tank.
Attack North Sea with submarine, 4 fighters, and a bomber.
Attack Gibraltar Battleship with Battleship, submarine, and fighter from ukraine. Also load tranny and take Gibraltar and offload the other infantry to Algeria in non-combat(if your opponents allow you to do this, some are anal about this.)
Non-combat:
Move two infantry from finland to algeria using the baltic transport. Also move the remaining infantry in Libya to Algeria.
Land fighter in Mediterranean and bomber in Algeria.
Depending what Russia has in Karelia it may be hard to hold both Western and Eastern Europe…if I’m left with a choice I’ll trade western with the allies for a few rounds.
