Forum:Leader Mod Question

For the soldier class, there is a mod for "extra team experience." I know you still get the experience playing solo, so that's cool. (I want to do my first playthrough on solo...)

But what I really need to know, do you get that extra experience for MISSIONS/QUESTS, or just killing enemies? I would really like to know if you get that extra XP boosts when completing missions and quests...
