I have a few comments to make on your very excellent enhancement project on the subject of explosions. I think the realistm of the effects of your explosions made by anti tank missiles and the like could be enhanced by adding more smoke and dust in the initial stages of the explosion, and increasing their duration. Smoke and dust should blast out along the ground on all sides of the blast. I've kind of been studying war footage to make sure my intuitions were correct, and I can share some of the (rather horrible) footage with you if you like.
Also, I think there could be some mixing enhancements made to the dynamic range sound pack. I find that- while they sound good- the explosions do not have nearly enough volume. While I know it's impossible (and unnecessary) to put the decibels of the effect to realistic levels, I think there could be more contrast between rifle fire and cannon fire, and especially shells flying through the air. It seems to me that the shells flying through the air are the loudest thing on the battlefield- which is sort of counter-intuitive. Also, I think it would be worthwhile to match the sounds of explosive round strikes (the burst sounds) with the rate of fire of the cannon that fired them. Currently, they're all over the place, and automatic cannon strikes sound like a mish-mash of random sound effects.
