Making a air siren is very easy right? You know how to make one right? Just change the comm tower's sound and then it is a Air Siren? That seems very easy huh? How about making a Air siren that only wails when there are enemy aircraft, eh? Stuck? Well, that's what this part is about. First open the toolkit and go to tanks, you know trucks, etc. Then open M1939 (You can choose, what to use, but it is best to use a AAA, but not the ZSU-23. It may be good, but does not fire much.)
First, give the AAA a name, like Air Siren. Press Okay. Then go to Ordnance and open a missile. Make that the missile can not do damage at all and when destroyed there is no explosion. Also make that the shape is invisible, like fire.sh, Okay, change the sound into a siren, (If you don't know how to, tough. It's just too easy to explain.)
Naw, actually just go into Ordnance, the name of your weapon, and go to sounds. Change the weapon loop sound, and that'll do it. However, you have to find the wav of a siren. ^_^
