We have wheel and track traits for getting around quickly, but why not a Leg Trait where its use means that the soldiers are dashing or evading in an attempt not to get shot, I suggest:
It takes a unit both actions to use the Leg Trait.
Movement is twice the units move value and can do nothing else.
The units Target is increased to 5+.
