Summary

When the President calls a State's National Guard into federal service, the President can set how long they must serve. Guard members and units must serve inside or outside the United States for that time unless the President releases them sooner. No member can be kept on federal duty past the end of their commission or enlistment. If Guards from more than one State are called together, the President can split how many come from each State’s Army or Air National Guard based on the States’ populations.
