>>Has the US ever deployed tanks and submachine gin fire during a natural (non-riot) disaster ?
I remember a blizzard when there were M-113s out on the highways rescuing people from cars. I think in Ohio.
That might have been during the Blizzard of 1978 ? It was the worse ever blizzard for Ohio. Saw a video special on that a few weeks ago. They had some vehicles that were stranded on the interstates that no one could get to.
