SFS Standard Mobile Aim [one-action] Feat 1

Source Player Core pg. 131
You’re rarely still, and you’ve learned to reliably hit your targets even while moving. You Stride and then Aim with a gun you’re wielding.

Traits

Traversal:These abilities can easily be adapted for other forms of movement. An action with this trait includes one or more Stride actions but can be easily adapted to other modes of movement. You can substitute a Burrow, Climb, Fly, or Swim action in place of any Stride actions if you have the corresponding movement type. (Any adjustments to the Stride, such as gaining a bonus or penalty to your Speed, still apply to the substituted movement type.)
