Supression should be changed to gun suppression and explosive suppression.
Gun suppression will have a small area of effect "blur the victims vision but less effective on those very near him".
Explosive suppression will have a wide area of effect and delay health regen on those near the impact area and block health regen of those who got hit or are inside the impact area
Both suppression will persist on main targets and be immediately removed from others if suppression is not sustained
Additionally fire support could gain a skill to reduce or be immune to suppression instead of the skill for steady fire from cover
