The military will not permit Biden to become President. It is true that Biden wants to disarm our citizenry. He will be arrested, and publicly at that. The military are true to their oath, and they are well aware that Biden is a traitor to the Constitution and our public trust.
It is much bigger than you are thinking or seeing. What you are seeing is the military responding to an external threat to our nation. Trump is in command, and he is defending America against a covert war. China initiated biological warfare against us last December, with help from high officials within our own government. They then began a cyberwarfare campaign against us. You will soon see myriad arrests within our borders of those who were knowingly complicit. The military are deployed to deter or counteract any orchestrated uprisings by Antifa and similar, and pre-positioned for defense of our homeland to deter the CCP from any overt actions.
