It is not against the law, the law says that the military cannot preform law enforcement functions. Defense of the border is not and should not be a law enforcement function.
18 U.S.C. § 1385 only prohibits the use of the Army and Air Force as posse comitatus and while 10 U.S.C. § 375 prohibits direct participation by a member of the Army, Navy, Air Force, or Marine Corps in a search, seizure, arrest, it doesn't mention the
National Guard.
They can be mobilized at the request of a state governor.
Repelling invasions it doesn't apply.
.
Millions of criminals sneaking across the border isn't an "invasion"? If you entered here illegally, you're a criminal, a trespasser, and an invader.
Which is why the military should be defending the border.
Bad idea.
We must keep the human cockroaches from stepping foot on American soil as our laws are way too pussified...when they do, they become our human pets for a year at minimum.
Soldiers standing guard on our border sounds cool....but the directive would be temporary and only issued by legitimate Presidents....The second a piece of shit Mexicrat is elected the directive would be lifted.
A wall will stand for eternity. Nobody could ever order demolition of a proven, effective, $25B barrier.
Further, much of the expense related to a wall would be that of a one time expense whereas the expense related to soldiers would be never ending.
Drones armed with pepper spray flying random patrol missions is the future of border patrol.
