Or maybe they're lulling us into a false sense of security by pretending to be terrible at throwing but they're actually ace at it?
We're not sure. They're track record is pretty abysmal.
This video from a training exercise in the Guangdong province of China shows one soldier who is lucky to be alive thanks to the quick actions of his instructor after his grenade throwing turns out to be less than great. Not that they seemed too bothered afterwards.
