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
