Warren "Bill" Gulley (November 16, 1922 – February 24, 2012) was an American military non-commissioned officer (NCO) who, in retirement, served (1968–1977) as the first civilian chief of the White House Military Office. In that position he amassed substantial political influence and established a sometimes feared reputation. Gulley later went into private business with Gen. Brent Scowcroft and others. In 1980 he wrote an exposé on misdeeds and embezzlement he'd witnessed during his career, Breaking Cover.
