Occurred on October 16, 2017 / Great Falls, Montana, USA
Info from Licensor: "I saw the helicopters moving slowly west, hovering above 10th Avenue South in Great Falls. The helicopters had mini guns mounted on the side of them, so that’s how I knew they were guarding a convoy. This convoy was most likely headed to a nuclear missile silo only 10 miles from Great Falls. I always find it interesting watching these things roll though town. We see them about once a month."
