The division's soldiers were issued strict orders to follow full containment procedures due to the viral outbreak, citing concerns about a possible pandemic. The hazmat-equipped soldiers augmented the security while West Tek researchers continued their experiments on the population, even as the mutating humans started to turn violent. Although the soldiers found West Tek authority to be detestable, at best, they followed orders and isolated the town with roadblocks and a secure perimeter.
The soldiers were not equipped to deal with the Huntersville horror, especially Sergeant Jake Bianchi. A day into the deployment, he was tasked with leading the extraction of a Huntersville resident for West Tek. They were not prepared to face feral mutants, one of which, a mother attempting to care for her infected son, lunged at Sergeant Taybet with a knife, forcing Private Sanderson to shoot her on the spot.
The situation deteriorated rapidly from that point as the population of the town started attacking the barricades and the soldiers. By November 7, the fighting convinced Sgt. Bianchi that something was wrong, that the town was actually a test site and the people had been used as guinea pigs. He vowed to get to the bottom of the mystery, which only earned him a rapid court-martial, charged with gross misconduct, dereliction of duty and insubordination. He was arrested two days later and replaced with the much more pliable, Sergeant Orlando Garrett, who showed respect and deference for West Tek.
