I reading history, didn’t Truman nationalize the national guard and sent them to Korea while the regular army starting drafting and training?
Washington was the first to use state militias to suppress the Whiskey Rebellion. It has been common to use the state militias, later the National Guard, for foreign and domestic conflicts. Shortly after Fort Sumter, Lincoln called for 75,000 militia to suppress the rebellion in the cotton states. That call impelled the Upper Southern states to secede. Kentucky declared as neutral. Maryland was occupied fairly quickly, and the Ohio militia captured much of what became West Virginia.
Very much so. FDR did the same thing before WW2...several such units (armored companies), including one from my state’s national guard, were organized into the 192nd and 194th Tank Battalions, and were subsequently lost in the Philippines.
