Traditionally, Red Scorpions abhorred the use of snipers, infiltrators, and other such sneaky shenanigans. They are a 'in your face' and 'up the center' legion, preferring to stand proud in the face of enemy fire (the almost universal Feel No Pain may have something to do with that).
If your Red Scorpions army contains NO sniper rifles, and will not be outflanking or infiltrating, AND it has 3+ tactical squads:
Once per game, and all in the same turn, all Rhino-chassied vehicles may move an extra 6" in the movement phase.
