Skull Probe

The Skull Probe is a military device utilized by Space Marine Chapters for reconnaissance. It appeared as a skull-shaped drone that hovered a meter above the ground, so it appeared to be a variant of the Servo-skull. It was capable of stealth, and quick flight that was faster than most units could move on foot, though it could not hover over obstacles. The are valuable to the Space Marines as a scouting unit for its mobility and inexpensiveness as a scout, though they were unarmed and quite fragile. They were able to temporarily neutralize an enemy structure, allowing the Space Marines a temporary tactical advantage, though it would destroy the skull in the process.

They appear only in the PC game Warhammer 40,000: Dawn of War.
