In European countries there are laws that a government take over your car, home, or horse if the military needs it urgently. I learnt about this at schools years ago and I don't know if USA has such laws, but pretty sure such laws were extended to laptops and solar panels. I think this is either NATO or EU regulation. It would be unwise to oppose a military at such times having such powerful tools.
> No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law.
So I don't think the US military can legally take over your house without your consent, except in time of war and then only if a law is passed.
But, experience from WWII shows that the government is gonna do what it wants, and the wheels of justice move slowly, and may not hold to what is right; the exclusion order that began the Japanese-American Internment was found to be constitutional, although detainment of loyal citizens was indeed found unconstitutional. If armed people demand use of your stuff, better to let them use it, and fight for compensation later.
In the US, all government power is derived from the US Constitution. The 3rd and 5th Amendments provide some protections of civilians from the military. But in practice, all civil rights only exist to the extent that they can be enforced. When martial law is enacted, there are no civil rights protections.
In the war of 1812 the president had to run away from Washington because of the British. His party wanted to sleep in a farm house, the farmer rejected the present. The president and his part left.
That’s just him being a good politician. He chose to be better than the other side and be seen to be better. It’s a trade off, in this case the hearts and minds won.
