Hey, Suppresive Fire has come up in some of our games and we believe we are doing it right from what we understand from the rulebooks, but a fully explained example would help us out a lot. Wording in the books is a little confusing...

Suppressive Fire
Models with Suppressive fire can attempt to scare or subdue an enemy rather than kill them. They are often equipped with special non-lethal ordnance such as gel rounds, shock grenades, tear gas and so on, or they may simply be trained to fire warning shots effectively. A unit with Suppressive Fire can opt to use it instead of shooting. To do so use the following rules:
· Pick a target within LOS and no further away than the weapon’s longest range band or long range, which ever is the shortest, and subject to normal targeting restrictions
· Do not roll any dice to hit or to wound
· Add together the Suppressive Fire values of every model firing at the target unit
· Add together all of the target unit’s remaining wounds, then add +1 to this value for every point of SZ above 2 that the largest single model in target unit has, and add +1 for each range band beyond short range that the target unit falls under
· The target unit then takes an immediate panic test modified by the total of number of wounds plus SZ and range modifiers, minus Suppressive Fire total.
If a unit shoots into a close combat using Suppressive Fire then each unit involved in the close combat must test against panic separately as if they were the target unit.
