Divizion

A divizion (dywizjon) is a word in several European languages, mostly Slavic, for a military unit in some arm branches, usually artillery and cavalry, being an equivalent of battalion. It should be distinguished from division, which is larger formation. The same word is used in some of these languages for a group of naval vessels (a division in naval usage).
