Plastun
A plastun or plastoon was a Cossack foot scouting and sentry military unit. Originally, they were part of the Black Sea Cossack Host and then later in the 19th and 20th centuries Kuban Cossack Host.
Early history
The tradition of foot scouts, vanguard troops, and ambushes, together with the term plastuny, belong to the early Cossack history of the Zaporizhian Sich and mentioned, e.g., by Vladimir Dahl in his Explanatory Dictionary of the Live Great Russian language. Plastun foot units were introduced during the Russian-Circassian War to guard and scout beyond the "Kuban Line", a frontier in the Kuban plains, against sudden Circassian raids.Later, the name "plastoon regiments" was applied to all Cossack infantry. In the Russian Imperial Army, whole plastun regiments were formed. Normally, Cossacks had to buy their horses and horse tack with their own money, and plastuns did not have these expenses. Despite this, regular plastun units were not popular, since they did not fit the traditional notion of Cossack pride. Therefore, plastun units tended to consist of poorer people.
