Aerial Reconnaissance "This is Showtime 11 to Stronghold 5-5. We've got a Serpent-Class assaulter approaching on your location. He fires at an Alarmingly fast rate and uses incendiary ammo. Bob & Weave; don't get burned."

Within mere seconds, a burst of 5 rounds impact the concrete around you, setting ground on fire and sending embers flying up. You can spot Serpent from afar, tauntingly waving at you before he readies another burst.
