Military Discipline Figging?
From a now-defunct and hence unlinkable web page about sexual use of suppositories comes this anecdote:
An old ex-Kings Troop chap told me that his father told him that before the first world war [ginger figging] was used when regimental squaddies were given unofficial floggings (cane or the birch) on the breech. In one case, rather than lose rank the ringleader opted for a private birching, two others were caned. A ginger suppository was inserted before the birching and the squaddie kept his breech well up and splayed.
