Background
Built roughly 40 years BBY M3-C3 (Mechy) was part of the "Republic's" movement to build the Grand Army of the Republic. Once assembled, programmed, installed with the applicable software and knowledge banks Mechy along with other supplies (Droids, power cells, bulk foodstuffs, and other "Exciting" goods) were shipped to Kamino. Over the years and treating minor scrapes/bruises, healing more major injuries, assisting/preforming surgeries, and even so mechanical or informational work. Once the deployment of the Clone forces occurred the support staff was deployed as well Surgical Droid M3-C3 was sent to Geonosis to aid in the aftermath of the First and far from last massive battle. Now recognized for its extra-ordinary intelligence and desire to preserve the life of the Clones and other Republic fighting forces, Mechy, has been recruited by the Intelligence branch to be sent on missions to increase the survivablity rates.
Motivation
Preservation of Republic life - M3-C3 is programmed to render aid to any and all citizens of the Republic if they require medical aid. Though in addition to this directive the Clone warfighters are included regardless that they are not "Technically" part of the republic.
After going such a long time without a Memory wipe and desire to be useful. Mechy's self learning brain has extended this to some mechanical issues as well.
Duties
RESCUE AND RECOVERY/EVAC & Personnel -
Quite similar to Its Motivation M3-C3 is deployed on missions in addition to aiding the base Medical Bay inorder to increase the chances of survival and provide aid to the local populations. Its primary functions are Medical in nature though over the years M3-C3 has expanded this to include Mechanical functions as well. What's more useful than a Surgical Droid? Well a Surgical Droid that can slice a computer and repair broken machinery of course.
Description
Mechy enjoys being of use to its treasured Clones whether that means providing medical aid, repairing or tinkering on equipment, or using its knowledge banks to educate or satiate the curiosity of people/lifeforms.
