Finnish Guards' Rifle Battalion (Finnish: Henkikaartin 3. Suomen Tarkk’ampujapataljoona, Swedish: Livgardets 3:e finska skarpskyttebataljon, Russian: Лейб-гвардии 3-й стрелковый Финский батальон, translit. Leib-gvardii 3-j strelkovyi Finski bataljon), colloquially known as Guard of Finland (Finnish: Suomen kaarti, Swedish: Finska gardet) was a Finnish military unit during 1829-1905 based in Helsinki. Continuing the legacy of Finnish Training Battalion (1817), it was part of the Imperial Russian Army and the only Finnish unit of the Russian Imperial Guard. Furthermore, for large parts of its history, the battalion was the only operational Finnish military unit. Because of its status as both a national showpiece and as a part of the Imperial Guard, it had a visible role in Finland.
The Finnish Guards' Battalion participated in four campaigns outside Finland. Two of these included actual combat: first in 1831 during the Polish November Uprising and for the second time, in the Balkans front of the Russo-Turkish War. The most famous of the battles it participated in was the battle of Gorni Dubnik in 1877. The unit was also deployed in 1849 to assist in quelling of the Hungarian Uprising and later during the Crimean War to guard the western border of Russia. However, it did not engage in action during these deployments. At the times of peace, the battalion was responsible guard duty in Helsinki and participated annually to the Russian military exercises in Krasnoye Selo near Saint Petersburg.
