If he's given a Jedi lead, it'll likely focus on offense. He was reckless, according to the Jedi Order, in leading some Jedi into war with the mandalorians. He led a counteroffensive against their incursion, and he was said to be brutal and efficient in leading the Republic forces.
If he's given an Old Republic leader ability, I'd assume it'd be more focused on synergy. Something that takes the strengths of each unit and uses them to make the group stronger. Something not unlike Hera lead for Phoenix.
