An aide-de-camp is a personal assistant or secretary to a person of high rank, usually a senior military, police or government officer, or to a member of a royal family or a head of state.

Adjutant is a military appointment given to an officer who assists the commanding officer with unit administration, mostly the management of human resources in an army unit. The term adjudant is used in French-speaking armed forces as a non-commissioned officer rank similar to a staff sergeant or warrant officer but is not equivalent to the role or appointment of an adjutant.
