(CNN) As the Missouri National Guard prepared to deploy to help quell riots in Ferguson, Missouri, that raged sporadically last year, the guard used highly militarized words such as "enemy forces" and "adversaries" to refer to protesters, according to documents obtained by CNN.
The guard came to Ferguson to support law enforcement officers, whom many community leaders and civil rights activists accused of using excessive force and inflaming an already tense situation in protests that flared sporadically from August through the end of the year.
The National Guard's language, contained in internal mission briefings obtained through a Freedom of Information Act request, is intensifying the concerns of some who objected to the police officers' actions in putting down riots. They broke out after the August 9 shooting of unarmed black teenager Michael Brown by city police officer Darren Wilson. A grand jury declined to indict Wilson in the case.
