The Finnish Defence Forces (The White Guards) are established as the official army of independent Finland, and Baron C. G. E. Mannerheim is appointed its Commander-in-Chief.

The Finnish Defence Forces (FDF) are the military of Finland. The Finnish Defence Forces consist of the Finnish Army, the Finnish Navy, and the Finnish Air Force. In wartime, the Finnish Border Guard becomes part of the Finnish Defence Forces.

The White Guard, officially known as the Civil Guard, was a voluntary militia, part of the Finnish Whites movement, that emerged victorious over the socialist Red Guards in the Finnish Civil War of 1918. They were generally known as the "White Guard" in the West due to their opposition to the "communist" Red Guards. In the White Army of Finland many participants were recruits, draftees and German-trained Jägers – rather than part of the paramilitary. The central organization was named the White Guard Organization, and the organization consisted of local chapters in municipalities.

Finland, officially the Republic of Finland, is a Nordic country in Northern Europe. It borders Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland to the south, opposite Estonia. Finland has a population of 5.6 million, the majority being ethnic Finns. Its capital and largest city is Helsinki. The official languages are Finnish and Swedish, the mother tongues of 84.1 percent and 5.1 percent of the population, respectively. Finland's climate varies from humid continental in the south to boreal in the north. Its land is predominantly covered by boreal forest, with over 180,000 recorded lakes.

Baron Carl Gustaf Emil Mannerheim was a Finnish military commander, aristocrat, and statesman. He served as the military leader of the Whites in the Finnish Civil War (1918), as Regent of Finland (1918–1919), as commander-in-chief of the Finnish Defence Forces during World War II (1939–1945), and as the sixth president of Finland (1944–1946). He became Finland's only field marshal in 1933 and was appointed honorary Marshal of Finland in 1942.
