True. It is just I look at one thing, then the other.
Revised plan:
Launch Viper
Activate Viper to Move to Sector Delta
Play Critical Situation Card
Activate Viper to Escort Civilian Ship
You can only use the Critical situation card at the start of your turn, replacing the movement phase. So you can use it first, then launch into a viper, then move a viper to delta, and you still have 2 actions. Since you can only use the CAG actions once per turn, if you activate the unmanned again, you have to pass the CAG title to someone else. You'll still have 1 more action to use, though.
