What's the point of suppression?
To recap - It prevents only one action - even if the unit has multiple suppression tokens?
It prevents a reaction.
It provides cover.
If the number of suppression tokens is greater than units and a hero is not attached that unit is retreating.
I know it's probably simple - but I'm having a tough time with point number one. What's the point in spending time putting multiple suppression bits on a unit of say 5 - especially if they are in hard or soft cover?
