Bullet physics / insane inertia
I think we've all seen how 5.56 rounds knock over walls on the public server, and when I was using the same modset (in the editor) to practice with the AH-6, enemies were launched a good 15 feet into the air if a mini-gun round hit them....
Vanilla Arma, especially with the broken armor system, can feel really bullet spongy...but issuing portable auto-cannons to soldiers doesn't seem like the right approach either

Does anybody know what causes these ridiculous effects? Is it a configuration problem, or some oddness with mods not interacting properly?
And maybe most importantly: Does anybody else see this as a problem?
