In wartime Finland, TK companies (the abbreviation TK comes from the Finnish word tiedotuskomppania, 'information company') were units under the information division of the Finnish army founded before the Winter War, which were active during the Continuation War and the Lapland War. Soldiers working in the companies were called TK men (Finnish: TK-miehet), whose civilian professions usually were journalists, teachers or advertisers. Some of the men were notable authors, illustrators and radio reporters. They acted as war correspondents, war reporters, cinematographers, photographers, illustrators, guides, announcers and announcement designers.
