The Strike Force is a special operations team founded by Nathaniel Barnes.
Captain Nathaniel Barnes and Detective Jim Gordon sought to create a law-abiding task force of the Gotham City Police Department to clean Gotham City up. Looking for members, they went to the Gotham Police Academy who Barnes and Gordon sought to recruit before they could potentially become jaded or corrupt.
Exploits as a group
After several arson-attacks on buildings, the Strike Force was assigned to take down whoever caused the attacks. The force soon surrounded Bridgit Pike before she could burn another building. Luke Garrett almost arrested her, but he was incinerated by her flamethrower and died after. The Strike Force was now fully assigned to hunt down Pike and bring her to justice. 
They'd interrogate many firebugs and arsonists through Gotham to no avail. Gordon was forced to ask Selina Kyle about Pike's status. She revealed Bridgit's next target. They cornered Pike and Bridgit refused to surrender, and eventually burned herself.
The Strike Force was assigned to protect the new mayor, Theo Galavan during his mayoral party from possible threats. They and many other cops defended the mayor from Penguin's thugs. Sal Martinez would eventually corner Tabitha Galavan on the top of the building, but he was brutally killed by the assassin. Penguin eventually escape, letting Gordon know that Galavan was a monster.
The Strike Force recruited many new members and their first mission was to scout a car with Barbara Kean, Gordon and Bullock. Some recruits were gunned down by assassins working for Tabitha Galavan, but they'd also kill many of the hit men. They later rescued Gordon and Leslie Thompkins from Ms. Kean and her henchmen. Kean was severely wounded during the battle, and they found out enough evidence to arrest Galavan.
Nathaniel Barnes plans to reassemble the Strike Force in order to hunt down Azrael (who happens to be the resurrected Theo Galavan).
