|This article is about the armored vehicle, for the type of Tech-Priest see Explorator|
The Macrocarid Explorator was a class of heavy vehicle used by the Mechanicum during the Great Crusade and Horus Heresy. The term itself was a classification of heavy armored and fully environmentally sealed vehicles used for combat, command, and exploration purposes by Magos.
No two Macrocarids were exactly alike, having been repeatedly redesigned and modified by their masters. In the earliest years of the Crusade however the Land Raider Proteus was the most common type of these vehicles, but as the Imperium expanded wholly unique hulls were added to the Mechanicum armory.
