Lance Corporal Ronald Church was an Orbital Drop Shock Trooper (ODST), later a Special Tactics and Operations (STO) Trooper, in the UNSC Defense Force. He was renowned among the other Helljumpers for his extreme sarcasm, satirical humor and general cynicism. Despite this, he was somewhat respected because of his survivalist talents and skill as a pilot, mechanic and technician. Among the ODSTs, he was almost always simply called Church, a name many thought suited him, because of his shallowness and seeming disregard for everyone around him.
