My wish is for a different sound to alert that airstrikes and reinforcements are available. Combat Mission games have a great sound alert for these. It is the scratchy sound you hear when you depress the radio button. You could use the same sound for both reinforcements and airstrike available. In the midst of the game, when many bell sounds are going off and you are trying to manage the battlefield, it would be nice to hear a unique sound to alert you so that one of these two important messages are not missed.
