“But, I am Canadian, so what do I know?
You do not know CRAP about the “militia” that existed in the United States. The predominant use of the militia was to fight the Indians and were also used in the Mexican War. I have ancestors who were in the “militia” who fought the Indians in East Texas and the Mexicans in Mexico.
They responded to the call to duty for a 90 day period, brought their own rifles, ammunition, horses and supplies and went to battle knowing that some of them were probably not going to come back.
Doesnt say the militia was meant to repel just indians and Mexicans. It may have been used to repel those groups, because they were needed for them.
My reading suggests anybody, like the Japanese during WWII if they had invaded America.
