That each and every free able-bodied white male citizen of the respective States,
For lack of a better word this is the "pool" to be chosen from. Now granted slavery existed at that time but that has been addressed along with womens rights.
Also note the individual called for service was to supply his own arms. If one didn't already have said weapons there were to be acquired by that individual. Not given to him by the state of federal govt.
Women and slaves/freedmen fought in the Revolution. Bobbies claim RKBA doesn’t apply to them is a spurious lie at best.
Able-bodied, white, male citizens, 18-45 years of age were not the "pool". They were the Militia. And they comprised about 20% of the population.
"If one didn't already have said weapons there were to be acquired by that individual. Not given to him by the state of federal govt."
That was the plan. But when the War of 1812 broke out, very few Militia members showed up with arms. Arms were provided to them by the federal government.
