b. ^ Although he admitted in his lifetime to IRA membership, he denied ever being Chief of Staff

a. ^ Hanley and Millar (2010) wrote: Goulding was "replaced by Garland after an Army Council vote in summer 1976. Long dismissive of the IRA's titles and formal military structure, Garland was reluctant to adopt the title of Chief of Staff; but he was now undoubtedly in charge".
