Give WW2 battles artillery sounds like Flying Circus

[FeuerFliegen]

I've noticed that in FC, the artillery has intense echos and sounds throughout the atmosphere.  The other artillery in the rest of the sim doesn't give the same sounds.  This would be especially nice in naval situations, which in real life echoed throughout the landscape, but in the normal Great Battles, it will be silent.

 

Could we get that same intense echo of artillery in the WW2 part of the sim?
