I have to throw the B.S. flag on the Summary execution RAW. The Idea that a character would heal upon seeing his buddy shot is just plain ridiculous! (It also has nothing to do with the TT rules and the way they work. Instead; I my game I use the following:
Summary execution:
If the player fails a fear or pinning test the Commissar may elect to Summarily execute a comrade with a challenging (+0) Ballistic skill test to hit the comrade. If successful the Comrade is immediately killed and the rest of the squad has any current fear or pinning effects removed. (Though they can still be affected by later fear causing events.)
Thoughts?
