Alternative names:

The think-tanks seen in the last episode of 2nd GIG are named Uchikomas (ウチコマ), similar to the Fuchikoma think-tanks used in the original Ghost In The Shell manga. In design terms too, they represent a fusion of the design features of the Tachikoma as seen in the series and those of the Fuchikoma, with "faces" and "abdomens" similar to the Fuchikoma and legs and "thorax" more akin to those on a Tachikoma.
During the early portion of the film Solid State Society, the Uchikomas are seen being used by Section 9 in a way similar to the way the un-evolved Tachikomas had been used. In fact, they were so unevolved that Batou found it irritating when they did not react like Tachikomas of old during a mission.
