So when a missions states the Imperial has say 3 Open groups I would choose for example elite Storm Troopers, Royal Guards, and say Trandoshans. What happens when one of those groups is killed? Can I later on once I've accrued enough threat redeploy them?
Also under special setup of certain missions when it states double the threat level and resolve an optional deployment, do I then spend that threat and put into play one of those groups? And then do I get my normal turn one base threat?
