Finally got a chance to break out the terrain and drive these rules around the table this past long weekend, and they are far more elegant than I realized on first reading. The rules for activation, holding actions, and suppression fire are individually quite simple, but the way they interact on the table makes for a deep and rich tactical environment. Our game ended in a one-sided victory as quantity exuded the quality all its own on my poor special forces troopers. Great fun.
The big head scratcher for us revolved around the use of suppression fire. My heavy was perched up on a rooftop with a clear fire lane down an alley. She could see a trooper peeking around the corner, he had two mates behind him out of sight, and was presented with the choice between suppressing either at the figure or at a point on the ground an inch away from the figure. She popped off a volley of CPMG fire resulting in three suppression markers near the entrance of the alley, which resulted in my opponent moving his squad around the other side of the building. No real effect on the game, but a few things didn't sit right with us.
Why would you ever fire at a single figure to suppress when you can just fire an inch away from the figure and suppress anything moving through that area for the rest of the turn?
Suppose a figure moves into an area affected by multiple suppression markers. Does the first figure take the hit on one marker only, or do all of the markers affect the first figure to move through the area?
