The Cadre

You're the Shas'o, and in the shadows far ahead of the frontlines you fight the enemy in and also to eliminate High Value Targets, infrastructures, save hostages, and capture enemy tech or retrieve your own, etc in order to make way for one of the Sphere of Expansions.

If you don't own the entry level models, use what models you own! Some Leaders show greater potential than others and might be tasked with a more senior unit to command.
