I ask to add some script commands to set/get (base) weapon sway intensity of given soldier unit. On my opinion, that would give us some great possibilities for creating interesting scenarios.
For example, if in a MP mission there are slots for SpecOps, regular soldiers and guerrillas, the ability to change players' weapons sway intensity in scripts/init would allow us to simulate the difference of the military skills of the roles. So the players, which play as SpecOps would be able to shoot generally more accurate (as they would have less weapon sway), while player in the role of a guerrilla would generally be inaccurate (as it would be difficult to be as accurate as SpecOps, because of higher weapon sway intensity).
That's not the only example where those commands would be useful. I think SP scenarios would benefit as well.
