Etymology
The word pioneer is originally from France. The word (French: pionnier) was borrowed into English, from Old French pionnier, which meant a "foot soldier", from the root 'peon'[4] recorded in 1523
It was used in a military sense as early as 1626–1627.
In the late 18th century, Captain George Smith defined the term as:
PIONEERS, in war-time, are such as are commanded in from the country, to march with an army, for mending the ways, for working on entrenchments, fortifications, and for making mines and approaches: the soldiers are likewise employed in all these things.
Most of the foreign regiments of artillery have half a company of pioneers, well instructed in that important branch of duty. Our regiments of infantry and cavalry have 3 or 4 pioneers each, provided with aprons, hatchets, saws, spades, and pick-axes.
