I kind of have this idea for a... I dunno? company? Battalion? I guess Regiment will be the most fitting size. It’s not big when it comes to man power but it has more clone medics than regular clone troopers. Even though they do at times engage in small-scale battles (mostly as an additional man-power or a “last stand” type of Force) they mostly deal with “medical” side of the war, like: organize trainings (overall safety, sex-ed, OSHA, etc.) for other GAR forces, creating field hospitals, shelters, field kitchens and especially - dealing with outbreaks of various diseases, not only among GAR soldiers and Republic allies, but also civilian population left to fend for themselves in wake of the Clone Wars.

The second-in-command is a Jedi healer apprentice nicknamed "Mercy”. He belongs to a species, that appears almost immortal due the fact that apart of long life-span they have highly potent healing factor (wounds heal in half the time... even those considered to be fatal), both high pain tolerance and threshold and high immunity (making him immune to most known deceases) that being said, his species is one of few in the Galaxy, allergic to Bacta (to the point submerging a person in it might be disastrous). That’s also why medics under his command quickly learn to use Bacta as a last resort after exhausting all the other treatment options, which is very helpful when they have to aid less advanced civilizations, their resources are spread thin or they’re forced to work “on the budget”.

The clone medic is named “40″. He was a sole survivor of a battle going awry (before 347th Regiment was formed). He was unconscious by the time another unit came on site to bury the dead, and if not for Mercy and his master (who, by chance, were present at the fallout) 40 would have been buried alive with the rest in a mass grave.

Despite the regiment being quite resourceful and chaotic when it comes to rule bending - the will bend over backwards to help people in need - they follow safety/medical procedures rigorously. Thus they often look out for other clones, like distribute protection at bars or cringe every time they learn some clone troopers don’t wash their hands at public restrooms.

Each time clone troopers/medics step out of the ship to the possibly infected zone, their armor is sealed with yellow strips (“do not tamper, safety seal”) - to indicate, when torn, the armor has been compromised. Affected clone trooper has to go under a strict quarantine, in some cases even used to study the disease when infected.

For the worse conditions, when air-filtration in their helmets is suspected to not be enough to secure their safety, they have bottles oh breathable air that can be strapped to the backs.
