Select: each such Titan may claim 1 enemy Titan (optional); an already claimed Titan is unavailable; claims are noted and shown to the opponent
Result:
while attacking its claim: you may re-roll Hit rolls of 1, Armour rolls +1 on those attacks
if a friendly Legio Gryphonicus Titan attacks an enemy that a different friendly Titan has claimed: that claim is void and this rule stops applying to that Titan (the source does not say whether this means the attacker or the claimant)
