From the vid commentary:

Virginia’s 2A: Section 13. Militia; standing armies; military subordinate to civil power.
That a well regulated militia, composed of the body of the people, trained to arms, is the proper, natural, and safe defense of a free state, therefore, the right of the people to keep and bear arms shall not be infringed; that standing armies, in time of peace, should be avoided as dangerous to liberty; and that in all cases the military should be under strict subordination to, and governed by, the civil power.

44-1. Composition of militia.
The militia of the Commonwealth of Virginia shall consist of all able-bodied residents of the Commonwealth who are citizens of the United States and all other able-bodied persons resident in the Commonwealth who have declared their intention to become citizens of the United States, who are at least 16 years of age and, except as hereinafter provided, not more than 55 years of age.
The militia shall be divided into three classes: the National Guard, which includes the Army National Guard and the Air National Guard; the Virginia Defense Force; and the unorganized militia.

I do not think that it can be any more clear, on how much of a violation SB16-18-64 will be.
