This paper describes the policy and principles for the provision of Military Aid to the Civil Authorities (MACA). It emphasises the importance of following the proscribed process in order to avoid possible political, legal, reputational and financial pitfalls. It outlines the broader military application of MACA before focusing on where the Defence Medical Services can contribute, drawn from recent experiences and identifying other capabilities that may be of utility. It draws heavily from Joint Doctrine Publication 02 and is quoted with the agreement of the Developments, Concepts and Doctrine Centre.
