Code of Virginia, Title 44 Chapter 1
All able bodied residents of Virginia age 16-55 who are U..S. Citizens are members of the militia (with exceptions for those holding some political offices, law enforcement, active military/Reserves, etc)
Again, since you didn’t seem to understand it the first time: All able bodied residents of Virginia age 16-55 who are U..S. Citizens are members of the militia.
Some people are in the National Guard, going through regular Army or Air Force basic and advanced training, serving one weekend a month and two weeks each year for pay. They are liable for call-up and overseas deployment by the President, or call up by the Governor for domestic duties. They have an 8 year military obligation.
Some people, not in the National Guard, join the VDF. They do online and brief in-person training, and serve, without pay, one weekend a month and two weeks a year. They are not liable for Federal call up, and the Governor uses them to supplement the NG in support roles during emergencies (during which they are paid). Except during a call up they can quit the VDF whenever they want,
but will still be in the militia just like every other able bodied Virginian.
Everyone else is in the Unorganized Militia (and most probably aren’t even aware of that). The unorganized militia has no training or uniforms etc. But are still liable for call up by the governor.
In short, with some exceptions, every able bodied Virginia resident age 16-55 IS in the militia and is OBLIGATED under penalty of law, to report for military duty as the Governor directs.
