William "The Bunk" Moreland is a fictional character in The Wire, played by Wendell Pierce. Bunk's character is based on a retired Baltimore detective named Oscar "The Bunk" Requer. Like his best friend Jimmy McNulty, Bunk Moreland is shown to be a thoroughly competent and generally moral detective, with similar problems related to infidelity and alcohol abuse. However, his vices aren't as severe as McNulty's and he is more mindful of the department's chain of command.
