Halo 3 armor

So I recently got Halo 3: ODST and I put in the Halo 3 multiplayer disk. I’ve been playing for a bit And reached the rank of private. The ODST helmet hasn’t unlocked yet, however. Is there something more I need to do? Will this happen when I try to unlock other armors?

Out of curiosity, did the Spartan Graduate achievement unlock?
