Defensive Engagement - **Restriction:** Titan in a Firmus Light Maniple
- **Limits:** a unit takes this check ≤1× per round; after a pass it is unaffected until the round ends
- **Timing:** an attack picks it as its target
- **Select:** 1 other Titan of the maniple, closer to the attacker than the first target is, and ≥50% visible to it; its controller may nominate it as the new target (optional)
- **Result:** the attacker may take a Command check (optional)
- Pass: it may still attack the original target, and picks targets normally
- Fail: the nominated Titan becomes the sole target for the whole round even if it could normally attack several units
