The Human Federation's Titan special ability is "Group Shield". If you bring more than one titan into a battle, despite all of them showing an active Group Shield ability, only one of the titans actually appears to benefit from this ability. Any of your other titans present in the battle do not take reduced damage to their shields and do not provide the damage reduction to nearby ships. TO REPRODUCE: I have attached a save if you want to see for yourself. Click end turn and choose to attack one of the planets in the Biks system. Allow the enemy to fire at your ships. You will see that only one of the titans takes reduced damage, has the ability pop-up when hit, and protects ships around it. The other titan is treated as though it has no special ability.
