Recruits
I prefer the wicked rather than the foolish. The wicked sometimes rest. -- Alexandre Dumas
Which brings to mind a possibly-apocryphal tale of the Prussian army's scheme for classifying recruits: They classified them on two axes: smart vs. stupid, and industrious vs. lazy. Smart+lazy became commissioned officers. Smart+industrious became non-commissioned officers. Stupid+lazy became cannon fodder. Stupid+industrious were taken out back and shot before they did any damage.
