Based on Skynets comprhensive human database and genetic information from the Human Genome project the organic exoskeleton was designed to provide a non threatening cover for its stealth support role. Initial reports from the battlefield detail the tremendous power the T-400 had to intimidate the resistance and strike fear into any enemy.
However design flaws meant increasingly T-400 were not returning from battle missions. Subsequent analysis of the design schematics revealed that Skynet had mistakenly based the design of the T-400 on male figures appearing on television circa 1980's in particular on mtv shows.
Further analysis of neural network chip recovered from incapacitated T-400's shows that the design was infact based on the construction worker appearing in the village people. Together with survivor reports from T-400 attacks it was surmised that T-400 preferred method of attack was to dispense with heavy weaponry and simply bugger the enemy to death. This together with the construction worker disguise and the hard hat resulted in massive casualties for the resistance.
A field report from the battle of nevada shows how four T-400's were able to route a 200 strong special forces team. Casualties who survived were unable to continue battle duty due to the inability to walk straight although some said the experience was not entirely unenjoyable. Of the 200 strong squad, 140 were unable to walk straight, 50 were retired and ten requested leave to have a same sex marraige.
The mystery of non-returning T-400's was finally resovled when reported surfaced that bootleg village people band was touring the country. On further inspection it was found the T-400's had gone A.W.O.L and formed a new dance troup devoted to the village people together with opening a Boyz'n'Uniform bar for same sex couples
Skynet cease production of the T-400 when they demanded tighter leather pants, better dressing rooms and bigger flower bouquets before entering the battlefield.
