Yes, this is the great problem with AT-ATs and eAT-ATs. They usually target the shield not the shield generator. But when the closest shield is disable for upgrade, they target the generator and walk to it through turrets and finish being killed before. Be careful and always see if all shields are operational before deploy them.
