The Space Corps of 2000 AD's Judge Dredd strip are a professional army which deals with conflicts and peacekeeping away from Earth. They have appeared in several stories, most notably Judge Dredd: Mandroid[1] and its sequel.[2]
They have been primarily shown fighting alien menaces off-world. Judge Dredd Megazine story Warzone[3] showed them being used as an occupying force on a space colony to prevent it gaining independence, constantly fighting against local insurgent groups.
When Space Corps soldiers are severely wounded, they will sometimes be turned into cyborgs: nicknamed "Mandroids", they are highly powerful and designed solely for combat. They also have genetically engineered soldiers, with Warzone showing an early, primitive-minded version of the Genetic Infantry program from Rogue Trooper.
Spin-off series "The Corps"[4] showed an off-world team of Mega-City One Judge-Troopers that are used in highly destructive combat operations, as well as black operations such as trying to end a Sino-Cit/Kleggs alliance.
