From GURPS Fantasy:
Orcs are to humans what humans are to elves: short-lived, shortsighted, aggressive, and disliked. All this makes them the natural warrior race of many fantasy worlds. With short generations and intense territoriality, orcs have split into many subspecies. These statistics are for an orc the same weight as a human, but about 2” shorter because of bowleggedness and a squat overall build. Other breeds may be larger or smaller.
