Hello here bandeide here, and i made some experiences around AA assets in the game. i used my Paratrooper squad along side a mortar configuration.
point is, it,s amazing, i played a map put down six planes and also killed 45 of infantry.
so, the best squad to use such AA feature is definitive the paratrooper, but a mortar squad would benefit a lot of it was well.
cheers.
