Swarm

Models in this unit that remain within their unmodified Move distance of each other count as a single unit (extended coherency). Additionally, all their weapons gain the Auto type if the targeted enemy unit is partially between 2 or more models of this unit.

> Example: A Swarm unit of 3 models fires at an enemy that is positioned such that at least two Swarm models are on opposite sides of it. All the Swarm’s ranged attacks gain Auto for that volley (making 1s count as crits).
