Master Rider
Codex Supplement: White Scars, p. 9
Even before he became a Space Marine your Warlord was a master at mounted combat, swift as the wind and impossible to unseat.
A model with this warlord trait and any attached unit gains the Move Through Cover special rule. In addition, the Warlord may re-roll the dice for its Initiative Test for the Hit & Run special rule.
