Operation Firestorm has a hole where you can fall under the map.

This is different from the tank running over you pushing you under the map, as this is a set location and has been consistent and reproducible. You don't fall continuously forcing you to redeploy, as you can get out of the hole by rapidly jumping/deploying parachute.

I have attached the what it looks like when someone is in the hole, what it looks like when you fall in, and the location.
