@squirecam Land in Syria and take Persia? Easier said than done! After a Taranto raid, Italy has only one transport remaining – if you land on turn 1, you get 2 units into Syria, which can often be immediately counter-attacked and killed from Egypt/Trans-Jordan. Even if they survive, there’s no guarantee that they’ll be able to conquer Persia.
Waiting until turn 2 to move into Syria doesn’t necessarily help – with only 10 IPCs, Italy can only build one extra transport, so now you’re landing with 4 ground units in Syria on turn 2. You can pick up the 3 infantry in Iraq on turn 3, and maybe land an infantry and a tank in Syria again on turn 3 so the tank can blitz to Persia on turn 4, which means you attack Persia on Italy’s turn 4 with 4 + 3 + 1 = 8 ground units plus maybe a couple of planes.
For its part, Britain can activate Persia on turn 1 with a loaded transport, meaning there will be 2 + 2 = 4 British units there on UK1. On UK2, Britain builds a Persian factory. On UK3, Britain builds 3 infantry in Persia, plus the 1 infantry from West India can arrive by foot. On UK4 (UK goes before Italy), you build 3 more infantry; 2 + 2 + 3 + 1 + 3 = 11 units defending Persia, not counting a couple of planes that can easily be stationed there as needed. So something like 11 inf, 2 fighters, even without any loaded transports coming up from South Africa or mech. inf. coming from East India.
Even with Italy going all-out against Syria/Iraq/Persia, and even with little/no reinforcements beyond just building the Persian factory and building infantry there, Italy is heavily outnumbered in attacking Persia. Much, much later in the game, after Italy has already taken Egypt, then the main Italian army can walk over toward Persia and cause real problems there – but that means the Persian factory has successfully produced for 7-8 turns, so it’s done its job for the Allies. The game will likely be decided elsewhere before the Italians can make to Tehran.
