准下士
In Commonwealth forces, a lance corporal is usually the second-in-command of a section. Lance corporals are commonly addressed as "corporal", with "lance jack" or "half-screw" (with corporals being "full screws") being common colloquialisms for the rank. Much like the use of bombardier instead of corporal in artillery units, lance corporals are known as lance bombardiers in the UK, Australia and New Zealand. The badge of rank is a single chevron worn on both sleeves or on an epaulette.
