What medal tier is the ancient one?

I was playing flood today and I was first infected and I met the requirements to getting this medal (survive an entire round as the flood and convert at least one spartan) and I’ve never gotten it before, so I was wondering what tier it is, whether it is a bronze, silver, gold, platinum or onyx medal. Does anyone know?

Halo 4 doesn’t have medal tiers. The medal doesn’t count towards any commendations either; it’s just for points for that match.

Silver.

Now try to get Gravemind (Infect all spartans without dieing)

Thanks for letting me know, and I don’t think I’ll ever get gravemind, that sounds way too hard, what medal tier is that, onyx?
