There is no audible alarm for inbound missiles. Why?
Well there is often a VERY late shout from the Gunner, but often it’s too late, and concerning infantry handheld missiles there is often no warning at all. The different original flyable choppers have a Threat Receiver System (TRS) that is somewhat different from chopper to chopper. Three of the choppers have different TRS’s. 1. In the Tiger you can bring both (radar and TRS) on the two MFD’s. The TRS screen will show a dotted diamond or other shape around a threat if detected and a solid if you are locked. Shoot and duck for cover. 2. In the Apache (US & UK) the two systems are on ONE display. The Radar has the described integrated TRS you see everything on the main radar. 3. In the Havoc there’s a little instrument separately right above the MFD, which works as the TRS. -Venom Viper As for the lack of warning for other types of inbound missiles, I tried to find out more about this from various online sources, and here is my best guess about what happens in the real world.
