OK, General.
What are your orders? Be specific.
The Army and the Marines are not policemen.
Virtually every country in the world uses their military to guard and protect their borders.
America should do likewise.
Police can’t prevent invaders from coming into our country....that’s the job of the military, specifically, the Army and the Marines, along the California/Mexican border, the Arizona/Mexican border, the border of New Mexico and Mexico, and, in the case of Texas, either on the Texas side of the Rio Grande or five miles south of the Rio Grande, on the Mexican side of the river.
Specific order? Apprehend any crossing into the U.S. illegally, detain them, fingerprint them, photograph them, and send them back. The Border Patrol is spread too thin.
End birthright citizenship.
And build the damn wall!
