I totally agree with you and it makes me sick how the developers have treated us, we are literally the only nation where the tech tree has not been divided due to laziness or incompetence in both cases it is unacceptable this treatment towards the players.
When the developers realised that the Italian tech tree was small they simply decided to exploit the fact that Ungeria was added to put in some Russian copy paste helicopters, to avoid making the effort is to add 2 Italian helicopters, furthermore the Ungerian helicopters are in the place of the Italian ones to increase the effort to get higher level helicopters.
