HT decided to add the ability to hear tank gunfire from aircraft.
However the gunfire and reload sounds were never separate in AH1.
One file plays the whole sequence.
All they have to do now is make it 2 separate sound files and you will hear tank battles from the air, without hearing them reloading.
Unfortunately with all the focus at the moment on performance issues with AH2 we just have to be patient and wait for the fix.
