Some of you asking for "better" explosions may be asking for explosions that look like the movies, and like less realistic games, which may not look at all like a real weapon employment. I'm not saying that DCS' explosions are right on, but be careful what you're expecting to see. Your expectations could be unrealistic.
Animals did wonders for ArmA2's immersion. When I see a rabbit running around in the middle of my mission, it feels real.
