Does a Slann that is nestled away in his block of TG get a 'Look Out Sir Roll' for things like template hits?
Yes, just like any other character in a unit L,OS! is used when a character in a unit is hit by a template (not just in TGs, he gets L,OS! in any unit he is in).
The only requirements for a Look Out, Sir roll are: 1. The character must be in a unit with five or more regular rank and file troopers and, 2. The character must by US 4 or less. So the Slann benefits from the Look Out, Sir! roll.
Awesome, thanks for the clarity on that one. Greatly appreciated. Did not know the US4 point. Thanks again!
Should say under the Characters section in the rulebook, don't have mine on me so I can't give you an exact page I'm afraid.
