The Black Tide series has something similar that they use to clear out zombies. It’s carried by helicopter with the shield protecting upwards, and it makes noise and flashes lights to attract the horde. They drop it off in the middle of an area they want to clear, and then pick it up a few weeks later.

Didn’t they also use shipping containers full of spinning blades and other surprises?
