Just an idea... I have an idea to make the radios more useful. There should be a warning on the radio (radio would have to be on and selected to a emergency broadcast channel) when a dynamic contaminated area will spawn in the vicinity. The warning should arrive 1 or 2 minutes before the first artillery sounds. It would give a tactical advantage for those who use the radios. You could have radios in car too with emergency broadcast too. Devs needs to make those radios more useful. On Takistan they could emergency broadcast sandstorms.
