Joe Kirkley

Private Joe Kirkley is a soldier under Harry Wells' command.

Biography
Wells' squad, including Joe, are dropped in the Scottish Highlands as part of a supposed training exercise. Joe holds the mission in contempt, as he is missing the football match against Germany for the "exercise." That night, the squad set up camp and pass around stories and jokes. The mutilated corpse of a cow suddenly drops down into the camp from a nearby ledge and frightens them. Upon inspection, Cooper notices that the animal was mauled rather than gunned down, and the squad decides to find how the cow died in the morning.

The next morning, the Squad follow a trail of blood left by the dead cow, until they see a flare go up into the sky. Following it, the squad finds the ravaged remains of their opponents encampment, finding a traumatized and hypothermic Ryan as the only survivor. Cooper exclaims that the camp is filled win equipment normally used in live animal capture.

As dusk falls, the squad hears the howls of approaching werewolves and retreat into the woods, where they come under attack by the pack. Bruce is killed, and Wells is seriously injured. They are rescued by a passing truck, driven by a zoologist named Megan, The squad seeks shelter at a deserted cottage to treat Wells' wounds.

At first, Joe and the other soldiers attempt to wait the Werewolves out until dawn, at which point the creatures will revert to human form. However, as ammunition runs out and Terry is taken, they decide to try and escape.

While Spoon distracts the werewolves, Joe runs to the barn so he and the others can use the Land Rover in the barn to escape. However, just as he gets into the Land Rover, he sees a werewolf in the barn devouring a still-live Terry. The Werewolf then bites Terry's head off and throws it at the windshield, terrifying Joe.

As Joe drives out of the barn and up to the cottage, he realizes that there is a werewolf hiding in the back seat. He then bravely jumps into the back of the Land Rover at the werewolf in a rage, but the monster ultimately wins the fight. Moments later, the squad finds Joe's bloody remains including his severed head in the Land Rover, being devoured by the werewolf before Megan drives it off with a handgun.

Cooper later says that Joe's body is gone, implying the werewolves took Joe's remains and devoured them.

Personality
Joe loved football greatly - Cooper noted that he practically "lived for it". He was openly and outwardly sullen about missing an England-Germany match for an apparent training exercise from the squad's drop-off - the situation's subsequent descent into a siege against the werewolves further fed Joe's frustration and dourness. Even after entering the cottage, Joe couldn't let go of his concerns about football, asking Megan if she'd heard who won the game. Terry jokingly claimed that putting up with Joe witnessing a penalty shootout was his own worst fear, while Joe claimed a penalty shootout was all that could unsettle him.

Joe and Terry appeared to be good friends based on their interactions on the squad's first night, and Joe was the first to angrily leap to Terry's defence when Ryan advanced on Terry for vomiting on him. Unlike Spoon, Joe considered their situation in the cottage nothing but "bone" ("Not very good"). Joe died defiantly fighting a werewolf with his bare hands, using his rage to fuel him while displaying bravery - likely pushed by the stress of their situation, his aforementioned building-up frustration, witnessing Terry's slow death, and being taunted by the werewolves in his final moments.
