Knight Excavator

The Knight Excavator is a type of Promethean Knight.
==Gameplay==
Two Knight Excavators spawn at the Ice CaveYouTube - Halo 5 | How to Kill the Knight Excavator and the Mining Site at the 14 minute mark, on the map Skirmish at Darkstar. They behave like standard boss Knights in other maps.
Knight Excavators are also possible encounters for a boss battle in Warzone Firefight.
