I sent an operative on a mission and he was injured but survived. How do you heal an injured operative?

wait they return to base then get healed up

time

 

they can't heal in hyperspace, so don't move them or have them in a moving ship. they'll heal at a rate of 1 combat point per day. when they're back to where they started in combat, you can use them again. people strong in the force will heal faster, 2 points a day, twice as fast, normally. but they just have to sit, which makes them vunerable to assasination/abduction etc. but you just have to wait, there's nothing else you can do.
