Captain Hansen Haile is a soldier in the Westmarch Military. Initially stationed at Bastion's Keep. A courageous and empathic leader, Captain Haile refused to send his men to their deaths during the battle with Azmodan. In Act III, the player first meets Captain Halie while he and his men are attempting to raise a catapult. Later, Captain Haile can be found at Rakkis Crossing, where he states that all of his men had died during the charge against Azmodan's lair. The player aids him in fighting off a mob of demons.
In Act IV, the player enters Captain Haile's home and rescues his daughter Kyla and her friend (a small boy from Bastion's Keep) and helps them escape to the Survivor's Enclave. Captain Haile appears later on, reunited with his daughter. He happily informs Kyla and her friend that the Reapers have finally been cleared out of Westmarch and soon will be defeated completely.
- Captain Haile is named after real-life game developer Paul Haile, who is close friends with several members of the Diablo 3 development team.
