I scoured the rulebook, and could not come up with a satisfactory answer to this question-
If a unit (like a Kommandogruppe) has a medic and mechanic, does the whole unit have to take the "special action" to preform the medic or repair task? In short, if I want to repair something with my mechanic, does every other model have to effectively sacrifice their action to do so, or can they take another non-movement action (like attack, or medic, etc)?
