But this is no movie. It's been a reality for Brickell residents these past few nights, and they've been capturing the strange occurrences on YouTube videos with names such as Miami Under Attack.
Turns out it's a military exercise conducted with the Police Department's cooperation to stage potential defense maneuvers in large urban environments, according to the military, which kept the details under wraps.
"We recognize this training has an impact on Miami residents and we appreciate your support during this critical training event," read a statement from the military.
The exercise ended Wednesday night. Here's a YouTube video.
