Cov served as the leader for Yayax Squad. He belonged to a group of squads that received training from Rav Bralor on the planet Kamino. Similar to the other members of his squad, he donned a Katarn armor with a gray-and-brown dazzle pattern. Brown coloring was also observed on his armor.
During the Battle of Coruscant, he provided assistance to Omega Squad alongside ARC Trooper Lieutenant Aven in the defense of the HNE Headquarters building against a Separatist assault. Later, he and the other members of Yayax Squad abandoned their posts and aligned themselves with Kal Skirata on Mandalore, where they took on the responsibility of farming and infrastructure maintenance at the Kyrimorut compound, working alongside Levet. Nyreen "Ny" Vollen transported him to Mandalore. Cov eventually developed feelings for Ruusaan Skirata, leading to a romantic involvement between them.
