@vendetta and @malmessi
This conversation has inspired me to give Italy additional nation-specific techs. Below is the current list of techs unique to Italy.
Italy tech category
Mare Nostrum: each Italian transport provides +1 support on defense to one destroyer or cruiser.
Autocannoni: allows Italy to build the autocannoni unit.
Bersaglieri: adds +1 to attack for Italian mobile infantry.
Italy's nation-specific Piston Aircraft techs
Sparviero (SM 79): Torpedo bombers' naval bonus is now 2.
Picchiatelli: Dive bombers' land bonus becomes 2. (Same as Germany's Stuka)
Aerosiluranti: torpedo bombers cost 1 PU less
The autocannoni unit is unique to Italy. Cost: 6 PU. Move 2, attack 2, defense 1, supports one infantry on attack. (Edit: the defense is now 2.) Also, this unit acts as an aa gun. In an air battle, an aa gun gets one shot only and fires on a 2. An autocannoni gets one shot only and fires on a 1. AA guns and autocannoni are the only two types of land units in the game which get to fire in an air battle. Below is a picture of a mobile infantry, a field gun, and an autocannoni.
