Batman (military)
The Imperial Russian Army used the term "denshchik" () for a batman. In the Russian Empire higher-ranking cavalry officers often chose Cossacks for these roles as they could be reasonably depended on to survive combat, and were also known for resourcefulness on campaign. However, they were hired help, and had to be provided with a horse also. The lower-ranking officers from serf-owning families brought a servant from home they were familiar with, particularly the infantry and artillery officers that did not require additional protection in combat, and tended to leave the servants with the unit baggage train. After the abolition of serfdom in the Russian Empire (1861), many officers went on campaign without servants.
