OOC: Ive promised to make the remainder of the RP realistic and i simply dont think this would be realistic. Sure, istalian subs could launch cruise missiles against defensive positions in Jakania during the amphibious assault and liberation mission. But not against the deltarian mainland simply because its to well protect from minor missile attacks (The HEAT system is still operational). Then. For Istalian bombers. How would those long range bombers reach Deltaria? They cant violate Solentian and Kalopian airspace. And even if they do. What would stop the deltarian airforce, which is not jet engaged with coalition air units, from intercepting those bombers before they can drop their payload?
I would propose the following: Istalian subs launch cruise missiles on deltarian defensive positions in Jakania during the coalition liberation operation and Istalian air units can bomb deltarian targets but ONLY when the ground and air campaigns against the Deltarian mainland have started. This is the most realistic approach i believe and would still show the Istalian people that Istalia is fighting along.
