Location

• All guardsmen are based in their home state or the state where they trained. The guardsmen are under the direct control of their governor and the President.
  
  

Function

• The governor of a state may use the National Guard to help protect aspects of a state's sovereignty and geography, such as its borders, but national borders are a controversial topic.
  
  

Example

• Many border states, including Arizona, demand to use the National Guard to protect the borders on the request of the President. This means that the federal government unifies National Guardsmen across the country and finances the protection of the border for a state or states. If the state deploys the National Guard to defend its borders, the state can only defend its own borders with its own guardsmen and resources.
  
  

Conclusion

• Although a governor can call their state's own National Guard troops, the cost in resources and manpower is not most likely not beneficial to the state.
