(WaG CRB pg. 324)
If you have two or more Troop Threats that share a profile, you can form them into a Mob as a Free Action on any individual’s Turn. The Mob then takes its turn immediately; the other individuals in the Mob lose their place in the Initiative order.
A Mob can split into smaller Mobs or individual Troop Threats as a Free Action. The new Threats act independently and separately in the Initiative order. You can’t split a Mob in the same Round it was created.
When a Mob attacks, make a single Test for the Mob as though it were an individual Threat. Add +1 bonus dice for every Troop in the Mob. The maximum number of bonus dice is half the number of Troops in the Mob.
A Mob can split their attacks between multiple targets. This action does not incur any DN penalty and is not considered a Multi-Attack (p.187). The GM must specify how many members of the Mob are involved in each attack when a Mob splits its attacks. Each group gains bonus dice equal to half the Troops involved, rounded up.
Mobs are only made up of Troops, and every individual in a Mob has 1 Wound. If your attack deals more damage than a Mob’s Resilience, your target dies.
The number of Icons rolled on an attack Test determines how many individuals in the Mob are hit. Every Icon rolled over the Mob’s Defense means an additional individual in the Mob is hit.
Every individual Threat in a Mob has the same Maximum Shock. If a Mob suffers more Shock damage than their Maximum Shock, one individual in the Mob is removed. If a Test to inflict Shock damage exceeds the Mob’s Defense, it hits multiple individuals, as with a normal attack.
If half or more of the Troops in a Mob are slain, they should make a DN 3 Resolve Test at the end of the Round. If they fail, the entire Mob flees, as though suffering from the Terror Condition, until they can pass a Resolve Test to rally.
Turning your back on the enemy is rarely a good idea. If a Mob rolls a Complication on a Resolve Test to avoid fleeing, 1d3 members of the Mob are slain as they are caught in a crossfire or trampled by members of their own unit.
