- Commissar execute activated only if squad has morale < 50%
This seems odd - the boost from using the ability isn't just to repair morale (although that is useful) it is to increase rate of fire / damage. Its basically a 20 req power It might be worth having a few conditions such as "with lots of other troops" (since it affects lots of people nearby) and "Has at least half squad strength".
I'm not sure how you can track if the squad is already affected by it (from it being used nearby) however.
