T'au Battlesuit - Battlesuit Nomenclature: There is broad range of T'au Battlesuits, and each has their own specialised tactical role. All nomenclature of battlesuits mentioned here are their Imperial designations rather than the actual names for the different battlesuit variants used in the T'au Lexicon. Imperial interrogations with T'au prisoners have yielded the term Her'ex'vre as the name in the T'au Lexicon for their single-pilot battlesuits. This roughly translates into Low Gothic as "Mantle of the Hero."Her'ex'vre was then transcribed phonetically into Low Gothic as the designation "XV," which forms the foundational prefix of Imperial nomenclature for the different types of T'au Battlesuits. Numerical designators applied to a type of battlesuit generally consist of one or two numerals placed after the XV prefix.The first number indicates the battlesuit's mass class, with "1" being the lightest and smallest battlesuit in the T'au arsenal, to "9" indicating a large, heavily-armoured and potently armed battlesuit. Those battlesuits which have a specific and confirmed specialised function are then given a second numerical designator, while those considered general combat utility battlesuits retain only the first numeral due to being considered the standard battlesuit of that mass class without any real specialisation.It is of note that some battlesuits may have a secondary operational role, and so a rare third numeral may be included in its designation. Please note that the recently introduced XV104 Riptide, XV107 R'varna, and XV109 Y'vahra Battlesuits are uniquely named, for their three numbers are meant to be read as 10-4, 10-7, and 10-9 respectively; with 10 being the mass class and 4, 7, and 9 being the designator of their tactical role.Below are the secondary numerical codes and the tactical function assigned to them that have been identified by the Imperium. Note that these numbers should be read as "XVx1" where the "XV" designates the unit as a T'au Battlesuit, the small "x" represents the number from 1 to 9 (10 in the case of the XV104 and XV107) indicating the mass class of the battlesuit, and the second numeral indicates the battlesuit's operational role.XVx1 – Designates a battlesuit of any mass class believed to only exist as a theoretical prototype or developmental model.XVx2 – Designates a prototype battlesuit of any mass class that has progressed to field trial testing.XVx3 – Designates a battlesuit of any mass class that has not entered mass production and has been assigned permanently to its pilot.XVx4 – Designates a battlesuit of any mass class approved for the command and control role, or is in the final stages of field-testing.XVx5 – Designates a battlesuit of any mass class outfitted with T'au stealth technology.XVx6 – Designates an air-space battlesuit unit of any mass class.XVx7 – Designates a battlesuit of any mass class intended to facilitate infiltration.XVx8 – Designates a fire support battlesuit unit of any mass class.XVx9 – Designates a battlesuit of any mass class designed for frontline assaults.XV10 - Designates the newest class of super heavy battlesuits.Using this system of nomenclature, the following Battlesuit designations can be rendered thusly:XV8 – Single pilot general heavy combat suitXV88 – Single pilot heavy fire support suitXV15 – Single pilot ultra-light StealthsuitXV25 – Single pilot light StealthsuitXV22 – Single pilot field test prototype light StealthsuitThere are also sometimes variations on the standard XVx naming convention consisting of a " - " followed by 2 other numbers, indicating a variant on the suit itself without altering its battlefield tactical role. For example, the XV8-02 Crisis Iridium Battlesuit is a variant on the standard XV8 Crisis Battlesuit with upgraded armour composites; it is not a battlesuit of mass class 8 that is currently in field testing stages of development, which would be indicated by an XV82 designation.
