The point is that ALL US reserve units are based at home until, like the National Guard, they are ordered to active Federal service overseas.
Their pay is from the Federal Government, their uniforms say "US Army", "US Airforce", "US Navy" or "USMC", their officers hold Federal Commissions and their oaths are to defend the Constitution of the United States of America as opposed to a particular US state or commonwealth.
They are Federal troops as much as the regular military and anyone who claims they are places to shirk dangerous service defames their achievements and insults their valuable service to the nation.
