Here is a wild one…
Catholic Mass: Allows Italy to ONCE call for the Pope to endorse Italy’s roll in the war. If succesful (1 in 6 on die) would create 1 INF in every neutral nation that was largely Catholic, controlled by Italy. Effected nations: Spain, Argentina, Peru, Venezuala. IPC amount for each effected nation raised to 1 each.
And this for your “frogmen”
Scuttle Crew: Would allow 1 INF to attack 1 Allied naval unit that PER INF that is adjacent to an Italian held territory containing INF (Italy specifies targets). INF rolls normal attack (1 in 6) and if succesful sinks 1 Allied ship. Such attack preceeds normal attack round. Failure is loss of Italy INF.
