Battlestar Galactica

Major Sherman Cottle, M.D. is Galactica's Chief Medical Officer (CMO). As the ship is operating with a minimal crew complement leading up to its expected decommissioning, Cottle is the only real physician/surgeon aboard Galactica, supported by a handful of medics such as Layne Ishay and Howard Kim. While Cottle acts as the Fleet's defacto Surgeon General, conducting inspections on other ships, there are also civilian physicians like Dr. Robert (The Woman King) and Dr. Stoffa (Hero), though the latter might be a clinical psychologist and not a medical doctor.

Cottle is somewhat eccentric and is considered a "bastard" among some of Galactica's crew, in addition to his penchant for being a heavy smoker, despite knowing the risks, and one not overly impressed by positions of power. He is, above all things, a healer. To him, nothing else really matters, be it rank, riches, or species. However, Cottle has shown a carring side that he hides under the gruffness. He comforts the mortally wounded Natalie as she dies by holding her hand and takes good care of Roslin. When Roslin brings this up, he shows he does care and is clearly affected by her words, but she has him return to his usual grumbling and smoking to save his reputation.
