If you take the time to reflect on LEGO news in 2014, you might remember the hotly anticipated LEGO Ideas release of Peter Reid’s Classic Space-themed set 21109 Exo Suit. Builder [E]ddy Plu took his shrink ray and cranked out this pint-sized version of a modern classic, and the icing on the cake is that it seats a microfigure from the discontinued LEGO games series. These particular figures originally appeared in the game 3842 Lunar Command. His build is instantly recognizable and incredibly cute.
I know that Peter suggested that, since all of the original five colors were revealed to represent job classes (kind of like Star Trek uniforms), green should represent mech pilots, but I disagree. There have been several official Classic Space mechs that came out long before green CS minifigs, and they were piloted by a range of different color uniforms. However, based on the teaser video, it seems clear that the two green CS minifigs are on a salvage operation, and salvage is not covered by the job/color scheme that was revealed.
