Background
Sergeant Doyle is a sniper and part of an American led NATO force stationed in London. Doyle's duty station is on top of the high rise along with Rooftop Sniper.
During the events of 28 Weeks Later (2007) played by Jeremy Renner
Doyle is on duty when he notices Andy and Tammy leave District 1 and cross into London. Doyle then notifies his chain of command. When District 1 becomes infiltrated with the infected, Doyle along with Rooftop Sniper and others fire at the infected attacking the non-infected and eventually the non-infected also when the command comes down to kill everyone. Doyle shoots and kills Rooftop Sniper when Rooftop Sniper is attacked by the infected and then Doyle abandons his post. He makes his way to the supply depot and tells Tammy, Andy, Scarlet, Sam, Depot Man, and Depot Woman that their best chance to survive is to leave during the night. Doyle then leads them out. He contacts Flynn and Flynn tells him he will pick him up at a park as air support is coming and they plan on bombing London. As Doyle and the others are making their way to the park, Depot Man and Depot Woman are shot and killed by a soldier. Doyle tries to get Sam to run from safety so he can get a location on the soldier, but Sam refuses. Andy then runs out and Doyle shoots and kills the soldier and the remaining group head towards the park. Scarlet tells Doyle that Andy or Tammy may be immune to the Rage Virus and it is important that they make it to safety. Flynn contacts Doyle and tells him a group of infected survived the bombing and are heading their way. When Flynn lands he tells Doyle he wont take the others and then flies off after telling Doyle he will meet him at the stadium but he repeats that he will only take Doyle. Doyle and the others head towards the stadium but are forced to jump into a car when they notice a smoke cloud coming their way. They then notice a group of soldiers advancing their way with flame throwers and Doyle pushes the car so the others can escape. As the car starts to pick up speed, Doyle is set on fire by the soldiers and burns to death.
