I've noticed in ArmA 3 as well as ArmA 2, that when you destroy a tower, it breaks apart. But the animation for the destruction is not good. It kinda moves like twigs, not steel. It doesn't look right somehow. If this is being replaced by PhysX great. But if it's still an animation, it should be done differently. And/or maybe have 8 different anims to choose from, randomly, so it doesnt look the same each time too.
This could apply to buildings etc, as well.
