Poruchik

Poruchik (Croatian: poručnik, Czech: poručík, Polish: porucznik, Russian: пору́чик, Serbian: поручник, Slovak: poručík) is a military rank in several Slavic countries, such as the Russian Empire and the Republic of Poland, equivalent to Lieutenant. "Poruchik" means "messenger", "officer for orders". This is a Slavic (Czech) copy of the term "Lieutenant" (locum tenens).
