*{{Endn|Note 2}}: It is unclear whether vehicle identification numbers distinguish between different vehicle types as different numbering sets, or if all vehicles of different types are counted in one list (for example, does a 2 on a Predator mean the second vehicle or just the second Predator?). Conflicting evidence is sometimes present within the same source (** [[Imperial Armour Volume Two - Space Marines and Forces of the Inquisition]])contains conflicting evidence, or identification numbers may be different on a case-by-case basiswith the meaning of the number differing between vehicles and Chapters. In ** [[Black Crusade: Angel's Blade]], pgs. 88-89, describes the [[Blood Angels]] [[2nd Company, Blood Angels Chapter|2nd Company]] is described to use as using identification numerals to signify a vehicle's number within its vehicle squadron.** [[Insignium Astartes]], pg. ~51 states that [[Ultramarines]] [[2nd Company, Ultramarines Chapter|2nd Company]] [[Land Raiders]] are numbered individually, in a separate list from other vehicles, implying that other vehicles (e.g. [[Predators]]) might also be numbered in their own lists.
