For the unititiated, I clipped this from Wikipedia about Rogue Trooper.
"Rogue Trooper is a science fiction strip in the British comic 2000 AD, created by Gerry Finley-Day and Dave Gibbons. It follows the adventures of Rogue, a G.I. (or Genetic Infantryman, a genetically modified, blue-skinned, manufactured elite soldier) and his three comrades' search for the Traitor General. His comrades are in the form of biochips (onto which a G.I.'s entire personality is downloaded at the time of death for later retrieval) and are named Gunnar (mounted on Rogue's rifle), Bagman (on his backpack ) and Helm (on his helmet). He is genetically engineered to be immune to almost all known toxins. He can submerge in strong acid unaffected, and is able to withstand a vacuum in his bare skin."
