Stunning Leader (WB, 1996)

Stormtroopers are trained to stun, not kill, priority targets in order to split enemy forces and hold the leaders for interrogation. Stun effects wear off, requiring efficient action.

If a battle was just initiated at an interior site, use 1 Force; for remainder of battle all characters of ability > 2 and all leaders (on both sides) are simultaneously excluded from that battle.
