Missouri National Guard Brigadier General Gregory Mason said his men were "seasoned soldiers" well equipped for the mission of protecting Ferguson.
Missouri National Guard troops were being deployed on Monday to the St. Louis suburb of Ferguson to try to restore calm to an area that has become a nightly scene of rioting and protests over the August 9 fatal shooting of an unarmed black teen by a white police officer.
Speaking at a press conference following the announcement by the Mayor, Mason said: "Our soldiers have been well trained and seen many missions of state response over the years."
