State adjutant general
Each state in the United States has a senior military officer, as the state adjutant general, who is the de facto commander of a state's military forces, including the National Guard residing within the state, the state's naval militia, and any state defense forces. This officer is known as TAG, and is subordinated to the chief executive. They do not have authority over police forces, only military forces.
Responsibilities
Each adjutant general shares a common responsibility for the state's National Guard plus a unique set of other responsibilities defined by the state's constitution, state statutes, and other state-level directives. In addition to their state responsibilities, each TAG is responsible to the federal government for the use and care of federal assets under the state's control. The National Guard Bureau in the Department of Defense provides a centralized administrative, funding, and procurement process to support the states' military departments. The Chief of the National Guard Bureau also provides input as a member of the Joint Chiefs of Staff on national military activities as they relate to the National Guard.The 54 adjutants general collectively form the Adjutants General Association of [the United States] which strives to enhance both state and national military security. A professional military guard organization, the National Guard Association of the United States serves to lobby both Congress and the Executive branch about common needs of the Guard as a whole and also provide support to members of the National Guard.
