The Spy is a Career in the Age of Rebellion Core Rulebook.
Soldiers of a different type, spies seek out the secrets of the enemy, undo the enemy’s plans, and hinder the enemy’s ability to do battle effectively. A single spy, in the right place, at the right moment, can save (or destroy) many thousands of lives, with a single well-timed action. Most military forces (along with governments, criminal factions, and large corporations) place a great deal of emphasis on crafting an effective corps of espionage operatives.
Jyn Erso, Dash Rendar and Garindan are all examples of Spies in Star Wars.
