A paramilitary is an armed, militarized-like force or unit that functions and is organized in a manner analogous to a military force, but does not have professional or legitimate status. The Oxford English Dictionary traces the use of the term "paramilitary" as far back as 1934. It has been used by many different political organizations from around the world throughout history. Paramilitaries have widely been synonymous with violence, political repression, ethnic cleansing, genocide and crimes against humanity.
