Background
CT - 2112 , was birthed as part of the Support Roles batch of clones, focusing more on mechanics and machinery, than direct combat capability. Blasting bucket-heads was great, but if the tank broke down, someone needed to fix it so they could keep blasting bucket-heads.
His clone batch was eventually meant to be split up, to supplement other squads.
CT - 2112 has found that he has a definitive love for machinery, vehicles especially. Every time he is given a new vehicle spec, he keeps imagining it in red, with flames along the side, and dual mounted flame-throwers along the front. The military strategist in him knows this would make them very inefficient, as the forward velocity of the vehicle would risk making the flames curl back into their faces. But the Other Part of his brain seems to think this doesn't matter, and is outvoted by the "It would look really cool." factor.
Motivation
The Republic: Per his conditioning and programming, CT - 2112 is motivated by his desire to support the Republic, and to insure it's continued existence against all threats, both internal and external.
Duties
Support
CT - 2112 focuses his time on making sure the squad accomplishes it's goals per their training. He focuses on making sure their equipment functions at top effectiveness, to help facilitate this goal.
Description
Like every clone soldier, he looks the same, though he has added streaks of red into his hair along his temples, moving towards the back of his head. He's yet to get a vehicle to put some flame paintjob onto, so he's making do for now.
