We have setUnitRecoilCoefficient since OA and it's fantastic. We need a similar way of controlling player's sway (aiming shake).

Examples for missionmakers/scriptmakers:

• simulating stress or despair of young soldiers, i.e whilst being under fire or witnessing something horrible, and thus being unable to shoot well;
• simulating not being familiar with guns (i.e a civilian units or unexperienced guerrilla don't control rifles as good as professional soldiers) and thus being unable to shoot well;
• simulating lack of sway when a weapon is right above some object (sway control is actually a missing part of my own weapon stabilisation/resting script) and thus being able to aim more accurately regardless of stance.
