Also ah 99 blackfoot and uh 80 ghosthawk should not be lockable (or at least not with ease) with long range air to air.
Just to prevent any confusion , arma 3 doesn't have chaff , chaff looks like a big glittering (not sure about that , maybe if hit by sunlight) smoke/cloud when deployed .
Last i checked artillery used reasonable ranges for their weapons , jets why shouldn't?
If full range implementation is not possible i would like to see at least something like 5-10 Km for short range and 30-40 Km or 50 Km for long range.
Long range air to air missiles can be evaded and out-maneuvered by very agile aircraft while for the short range ones is less likely.
