Lovik
From Halopedia, the Halo wiki
Summary
Corporal Lovik led second squad in a recon mission on a Covenant base that included Private Riley, Private Manuel Mendoza, Private Kappus, Private Bicenti, Sergeant Johnson, and Private Jenkins.
He was among the first group of humans attacked by the Flood, and desperately raised the Sergeant and Captain Keyes over radio, though incoherently. He was infected and later killed in the detonation of Installation 04, or through the exploits of the Master Chief, or possibly by other Marines or the covenant.
