MedicalDoctor: Recall if you have to reaction time to take cover from a thrown grenade

You do, but there's no cover to take. But like any good medic, you still do what you were planning to do when you ducked into cover, which was to call for medical help ASAP, so you can salvage a little of that cover-taking action.

RedDwarf: Keep up the pace. Heart pounding, blood rushing, put what you do best to good use.
