The National Guard of the United States is controlled by the federal government. The National Guard of Oklahoma is controlled by the Oklahoma government. They are two different things. When a National Guard unit is brought up on Title 10 U.S.C. orders it becomes a part of the National Guard of the U.S. However, until such time, that unit is under the control of its state's governor and adjutant general. Regardless of whether or not the governor can prevent the president from federalizing a unit, until federalized by the president they are under control of the governor, and as per the Militia Act of 1903 the National Guard IS part of each states' militia. I am a officer in the Oklahoma National Guard, I have orders from both the Governor and the SECDEF appointing me. Because of my office I am familiar with how the Guard operates. I assure you that the National Guard is a part of the state's militia.
