H. Ryan Memorial
From Halopedia, the Halo wiki
H. Ryan Memorial is a Bungie.net campaign medal available in Halo: Reach. It is earned by killing wildlife in a Campaign mission. It is represented by a bloody Moa. The medal does not appear in-game and can only be viewed on Bungie.net. It is named after the ex-Bungie LLC President Harold Ryan.
On March 31, 2012 Bungie.net ceased updating Halo game stats and player records, transferring all record-keeping responsibilities to Halo Waypoint. As H. Ryan Memorial could only be viewed on the site, it is effectively no longer awarded.
