Private Qillen Bel-Jenta is a Tanker with the nickname "Killswitch".
Bel-Jenta is attached to Downfall Company, coming under Stroun Coren's One-Four Charlie fireteam along with his friend and comrade Kaffen Groll.
The surname Bel-Jenta suggests that Qillen has come from a relatively privileged background. It is not known at this point precisely how he came to be a Tanker, a role at which the elite members of Imperial Combine society would traditionally turn up their noses.
Given that Downfall was deployed to the surface during the Second Liberation of Mibes, it is reasonable to assume that Bel-Jenta was one of the Tankers encountered there by Elm Caden and his team. The same can be said of both Operation Keystone, which visited the surface of Guathelia, and the mission to the Viskr homeworld (→LOTD, TRD).
Bel-Jenta was present during the investigation at Forge Ruinous, when CAGA and Tanker assets were deployed to the surface of Lopama in order to discover the whereabouts of a missing Tanker platoon. He was responsible for providing live mapping data to his squad during their insertion into the facility. It was Bel-Jenta who inadvisably shot the captive Herik Pammon prior to the end of the mission (→FSS).
Bel-Jenta took part in Operation Sabre on the surface of Palanda Ire, and towards the end of that mission he cleared a tall building for use by sharpshooter Euryce Eilentes. He later acted as a member of a ground strike team during the Siege of Damastion (→FSS).
