From the publisher's website:
Use your knowledge to lead Rebel forces with the Instructor Specialization Deck for the Star Wars®: Age of Rebellion™ roleplaying game. Available through our in-house manufacturing division, each Age of Rebellion Specialization Deck includes twenty talent cards for a single specialization. Thematic art on every card helps immerse you more fully in the Star Wars universe. With these cards, players and GMs can easily put the talents of the Rebellion into action in the war against the Empire.
Instructors possess greater discipline than most members of the Rebellion. They’re equally comfortable teaching in classrooms, running drills, and commanding troops in battle. In every situation they take care of others before themselves, and may even pause during the fray to administer field medicine to the fallen.
The Instructor Specialization Deck contains:
• 2 cover cards (including a reference guide for each deck)
• 20 standard sized talent cards
