Information: - The second-in-command (2i/c or 2IC) is the deputy commander of any British Army or Royal Marines unit, from battalion or regiment downwards. He or she is thus the equivalent of an executive officer in the United States Army. This terminology is also used in many other Commonwealth armies. - Lieutenant - General Sir George Arthur , 1st Baronet KCH PC ( 21 June 1784 -- 19 September 1854 ) was Lieutenant Governor of British Honduras ( 1814 -- 1822 ) , Van Diemen 's Land ( now the State of Tasmania , part of Australia ) ( 1823 -- 1837 ) and Upper Canada ( 1838 -- 1841 ) . He also served as Governor of Bombay ( 1842 -- 1846 ) . - A lieutenant governor, lieutenant-governor, or vice governor is a high officer of state, whose precise role and rank vary by jurisdiction, but is often the deputy or lieutenant to or ranking under a governor a "second-in-command". A notable exception to this would be in Canada and a few other Commonwealth realms, in which the lieutenant governor is the representative of the monarch in that jurisdiction.
