SKYNET's catalog of combat units included standardized designations that took the Resistance many years to understand and decipher. Not all designations were known and even after the fall of SKYNET at the Battle of Cheyenne Mountain in 2029 AD, review of SKYNET's data still left a lot of questions unanswered. Listed below is a partial list of standard attributes shared among 90% of SKYNET's regular production models, especially the combat units. These units were assigned a two part production indicator known as a Unit Indicator Lead (UIL) and Unit Indicator Trail (UIT). The UIL was a four to five digit indicator consisting of a leading Class designation followed by a three to four digit Generation, Series and Version number. The second part of the standardized production identifier consisted of a three to four digit model number based on model specific production standards.


Unit Indicator - Lead : Class . Generation . Series . Version


The Unit Indicator Lead could be used to quickly identify a unit and the UIL and the UIT could be found as a three to four digit tag somewhere on any Machine encountered or as a virtual tag imbedded in the base operating system and control software.  For quick reference, combat units included the following design designations: (H) Hunter-Killer, which denoted a large scale area pacification combat unit and (T) Terminator which denoted a smaller scale, anti-personnel oriented combat unit.


The T800 Endoskeleton combat unit designation breaks down as follows :


T = Class Terminator

8 = Generation, 8th Generation

0 = Series (see below)

0 = Version (see below)


Additional identifiers associated with standardized SKYNET unit production and seen in the UIL include:


H = Hybrid

X = eXperimental

P = Prototype


The Unit Indicator - Trail (UIT) was composed of the Model callout which consisted of three or more digits composed of both letters and numbers. Generally displayed as a "Model" number, the actual digits behind the "Model" number indicated much of the unit's overall construction and makeup.


Model (3 digits), in this example, the designation of "Model 101" indicates that the T800 Endoskeleton combat unit is (1) an Infiltration / Infiltration unit, (0) is built from a Base design template and (1) has a single CPU controlling the design.


1 = Mission profile (see below)

0 = Design template (see below)

1 = Number of CPUs (see below)



Notes on the UIL / UIT designation.


Series Each Series increment was marked by a large change in the basic operations or capabilities of the unit. All Series start at a baseline of zero (0) and move forward in increments of one with 0 being the base model, 1 being the first Series, 2 being the second Series, etc. Each increment represents a significant change in the design indicating marked improvement in the model.


Version Each Version increment is marked by a small change in the capability of the unit, generally in the hardware or software but sometimes in the design itself a change in version was never enough of a change to warrant a new Series to enter production.


While the Series and the Version will differ from model to model, only the Version will use additional letters to signify changes. Each Version number can have 26 sub-ratings within its level category thus the T615D Model 202 represents a Terminator, 6th Generation, first Series, fifth Version, D level upgrade of the fifth Version, APU Area Pacification Unit, base design template, controlled by two CPUs.


Model number was broken down into three or four digits depending on the design. The model number indicated the mission design of the unit, the volitional state of the unit and the number of CPUs controlling the design.


Thus, the UIL / UIT indicator of a T800 Model 101 Endoskeleton combat unit can be broken down as follows:




T = Terminator Class

8 = 8th Generation

0 = Base model

0 = Base Version




1 = Infiltrator

0 = Design Template (0 denotes base, incremented forward)

1 = One CPU used for control of design



Model identifiers - First Digit - UIT


0          =          SPU - Sector Pacification Unit - large scale general combat

1          =          Infiltrator - specific role anti-personnel - infiltration, specific target elimination capable

2          =          APU - Area Pacification Unit  - general role - anti-personnel

3          =          AMU - Air Mobile Unit - Aerial

4          =          Recon / ELINT
