Alternate sound alerts for "Air Stirke" & "Reinforcements"

[Captiva]

I would love to have a separate sound to alert me of the availability of an Air Strike and when Reinforcements have arrived. When things "hot up" I often loose track of the messages and just hear the bell sound going off. Maybe the scratch sound that is made when you depress the talk button on a walkie-talkie be nice. You could use the same sound for both Air Strike and Reinforcement arrival. Just something to alert you to these two very important messages.
