Let any vehicle explode, or any missile or grenade, and notice the lack of oomph, and especially the weird "peeewwww" noise the explosions make at impact.
I´ve provided two video snippets detailing the explosion sounds ingame.
It is difficult to find Videos online that have clear sound evidence for explosions (usually someone is yelling over the sound).
However, I hope that this can be addressed nonetheless, and the "bang" part of the explosions at least be made more prominent. That a rifle sounds less impressive than a tank exploding needs to be turned around.
And thanks for your good work so far!
