Sometimes you want to eliminate your opponents with pinpoint accuracy… and sometimes you just want to reduce their position to a smoking crater. This spring, you’ll have the firepower to do both. Fantasy Flight Games is pleased to announce the upcoming release of two new expansions for Dust Tactics, the tactical miniatures board game of explosive battlefield combat!
With the Allies’ Special Ops Rangers and the Axis’ Special Ops Grenadiers, you’ll wield the deadly precision of expert snipers and the superior tactics of long-distance observers. Each expansion contains two units consisting of two figures, for a total of four figures per box.
