Tachikoma
Encyclopedia : T : TA : TAC : Tachikoma
A Tachikoma (タチコマ) is a fictional AI walker/roller tank in the Ghost in the Shell universe.
Design And AI
Tachikoma are as large as an average sedan, are painted blue and have four "eyes" fitted on the surface of their bodies. They are controlled by individual AIs, are capable of speech and generally exhibit a childish, curious, joyful and active personality, although they are consummate professionals in the field. They normally operate as independent units and receive orders from human agents, but they can also be directly piloted from a cockpit in their abdomen.
Tachikoma have four legs and two arms. They can move by walking, or they can drive at high speed by using their wheeled footpads, and are apparently street legal. Other abilities of the Tachikoma include jumping great distances, sticking to vertical or inverted surfaces, and grappling/rappelling using their adhesive string launchers. Their movements when walking and jumping were modeled off of a jumping spider.
Despite the fact that Tachikomas probably weigh a few hundred pounds each - even without an operator - they are shown scaling simple wire fences and jumping from great heights onto rooftops without causing any structural damage whatsoever. However, this property is shared by other individuals in the series.
Standard Tachikoma equipment includes a light machine gun mounted in the right arm, a secondary weapon in the "snout" (either a rocket-propelled grenade launcher or a six-barreled minigun), and a built-in optical camouflage device.
Though they possess individual artificial intelligence, every night they are synchronised, so they start the next day with identical conciousnesses that are each the sum of their total collective experience & development. This leads to identity confusion, since each Tachikoma has the same memories.
A notable paradox arises from this synchronisation, however. Though the Tachikomas have identical memories, their personalities and opinions are distinct. During the Stand Alone Complex series, a few episodes are entirely devoted to discussions among them.
These separate personalities reveal three 'main' Tachikomas, with the main voice acting. The first one is Batou's Blue Tachikoma, which has a personality of a hyperactive child. It is curious, inquisitive, and tends to get many 'bright' ideas. Unfortunately, these ideas seem bright only to itself. Then again, it did manage to provide a rather interesting definition of God. The second major Tachikoma is possibly the Major's. This Tachikoma is logical, and tends to be the one who points out the flaws in the thinking of Batou's Tachikoma. In other words, it's the straight man to the Blue Tachikoma. The third Tachikoma is simply there and really doesn't do much, other than complete the trio. There is also a fourth Tachikoma with a distinctive personality, who is a bookworm and an intellectual. Its body was taken apart during the experimentation incident, but its AI has presumably been saved for further analysis.
The dynamics of the relationship between the Tachikomas and their leader is summed up quite nicely by a quote from Episode 2, Testation: "The Major doesn't like it when we chatter." Even though it seems that the Tachikomas don’t comprehend the concept of “labor”. - But what might be when they probably acquired ghosts?

Background
Tachikoma were introduced in the [[Ghost in the Shell: Stand Alone Complex]] TV series.[[Ghost in the Shell: Stand Alone Complex (1st GiG)|Stand Alone Complex]]
In episode 12 of the first season, one slightly-malfunctioning Tachikoma goes on a joy-ride through the city where it meets a young girl named Miki who is looking for a lost dog. The episode is mostly comedy but turns serious, with the Tachikoma attempting to understand sadness and death. In a later episode, the Tachikomas argue among themselves over which met Miki, since they all have the same memory.
Batou has the most affection for the tanks, picking out one tank as "his" and spoiling it with natural oil instead of synthetic. This is what causes his to go haywire later, when the natural oil dissolves some of the proteins in the Tachikoma's AI neurochip. On the other hand, Togusa, the least cyberized of the Section 9 staff, holds a more dim view: "they're just machines." Aside from leading to an indignant outburst from the Tachikomas (who accuse Togusa of bigotry), it sets up something of an antagonistic relationship between Togusa and the tanks, which is revisited in an episode in season two. Major Motoko Kusanagi holds the most pragmatic view of all. Her only regret following the Tachikomas' suicide attack is that she didn't get a chance to dive their AI, and discover whether or not what they had acquired was really a "ghost".
The Tachikomas also show a slightly mischievous side in episode 15, Time of the Machines. They confuse a Section 9 operator with a self-referential logic paradox also used in the Star Trek television episode, I, Mudd. In that episode, Kirk and company escape from the planet by confusing an android with the statement along the lines of "Everything I say is a lie, and I am lying." The admin drone, which has a much simpler AI, is utterly confused and left stymied, allowing the Tachikomas to steal a piece of equipment left in the drone's care and ridicule the drone for being fooled. Interestingly enough, the drone does not completely malfunction. She simply sits down and keeps thinking, apparently stuck in a logic loop.
By the end of the series, the Tachikoma fleet start approaching sentience; all are sent back to the lab for dissection, amidst fears that they are no longer fit for combat duty. It is the use of natural oil in Batou's personal Tachikoma (all other units used synthetic lubricant) that acted as a catalyst for the behavorial anomalies that began to manifest as sentience. The Major (Motoko Kusanagi) subsequently bans the use of natural oil prior to the later decision to halt deployment of Tachikomas in field ops.
Three Tachikoma survive the lab analysis, (one blue, calling itself "Batou's Personal Tachikoma", and two others, repainted yellow and silver) and prove their worth when they abandon their new civilian jobs to save their imperiled comrades, without explicit orders to do so. The silver Tachikoma is destroyed on sight when it finds Batou under attack by an Armed Suit, a bipedal power-actuated armored exoskeleton. The blue and yellow Tachikoma combine their efforts to save him, and conduct a desperate and ultimately suicidal attack against the Umibozu, while Batou watches from a nearby terrace with a stricken look on his face. This selfless act is the last thing they ever do. Because of their devotion, the collective Tachikoma consciousness is restored from the backups made during the dissection process and loaded into a new fleet, which appears in the second season.
[[Ghost in the Shell: S.A.C. 2nd GIG|2nd GIG]]
In the second season, [[Ghost in the Shell: S.A.C. 2nd GIG|S.A.C. 2nd GIG]], the enforced synchronizations among Tachikomas are halted, since Motoko Kusanagi allows them to preserve their own personality after acquiring sentience in the first season. They can still share information and sensation with synchronization if they want to, and also specify which area to share. The Tachikomas are also outfitted to perform complex networking tasks, including netdiving, to aid Section 9. Several episodes featured the Tachikomas operating in the nets as bots, manifesting in their physical form but navigating the net as though flying through it. The final episode indicated that while operating within the nets, they could not inhabit their physical units.
It is hinted that Tachikoma units developed ghosts. During the finale of 2nd GIG, while ordered to create a repository in cyberspace for the memories (and hopefully, ghosts) of all refugees of Dejima, they secured instead their own memories within the netspace and selflessly sacrificed their AI satellite to prevent a nuclear explosion. A fellow AI, the cyborg Proto, knows what's happening and says he'd swear they had ghosts right before the satellite and missile make impact.
The destruction of their satellite resulted in them being permanently destroyed and replaced by the Fuchikoma/Tachikoma hybrid, Uchikoma. Whether or not their memories will resurface in the upcoming [[Ghost in the Shell: S.A.C. Solid State Society|S.A.C. Solid State Society]] is pure speculation. However, there was one clue given in the final episode of 2nd Gig. One Tachikoma can be seen placing a globe with the label ALL TACHIKOMA MEMORIES in a large memory storage unit in cyberspace. So it could be that their memories did survive, but the behavior of the Uchikomas in the final scenes of 2nd Gig did not indicate this. The Uchikoma had one line, addressing the Major as "Sir."
As a side note, during the Tachikoma Days short for the final episode, one Tachikoma, presumably Batou's from its behavior, found itself alone in a white area which did not appear to be what they viewed as the afterlife. While fully colored and shaded, it encountered a blank line Uchikoma in a shower of rose petals. This may indicate a planned merging of the two AIs in the future or the evolution of the Uchikomas.
Tachikoma Days
Tachikoma Days (タチコマな日々, Tachikoma na Hibi; also known as Tachikoma Specials) are a series of comedic shorts attached to the end of episodes of [[Ghost in the Shell: Stand Alone Complex]], featuring the antics of the Tachikoma think tanks of Section 9 and usually involving plot points from the episode it accompanies. The average Tachikoma short takes up a little over a minute, and one is attached to every episode. [[Ghost in the Shell: S.A.C. 2nd GIG]] (the second season of the TV series) also has Tachikoma Days at the end of each episode.Tachikoma Days is not aired on Cartoon Network's Adult Swim programming block, of which Stand Alone Complex and 2nd GIG aired on. However, they are shown on Adult Swim's free webcast programming service Adult Swim Fix during the Friday night premiere block. Australia's Cartoon Network's Adult Swim Tachikoma days are broadcasted with each episode.

Trivia
- On Episode 16 of the Tachikoma Days short-animation, one of the Tachikomas holds a book called "Anti-Oedipus". It is a reference to Gilles Deleuze's and Felix Guattari's book Anti-Oedipus: Capitalism and Schizophrenia.
