I'm currently building a raven guard army and have just finished building a seeker squad and I was wondering which markings (if any) legion seeker squads use as I the only artwork I've found of a legion seeker is an alpha legionnaire that has a shoulder with bonding studs so only the legion symbol is shown. I'm currently torn between using the recon iconography as they fill a similar battlefield role or the special unit designation iconography as I feel that seekers fit that description as well. Any advice is much appreciated.
