While this model is leading a unit, each time a model in that unit makes a ranged attack, re‑roll a Hit roll of 1.

You can re‐roll Advance rolls made for this model’s unit. In addition, each time this model’s unit makes a Normal, Advance or Fall Back move, models in that unit can move through models and terrain features. When doing so, they can move within Engagement Range of such models but cannot end that move within Engagement Range of them, and any Desperate Escape test is automatically passed.
