Sissi is a Finnish term for light infantry which conducts reconnaissance, sabotage and guerrilla warfare operations behind enemy lines. The word sissi, first attested in the modern meaning "patrolman, partisan, spy" in 1787, comes to Finnish from Slavic and refers either to a forest bandit or his yew bow.

The Finnish Army Sissi units are trained to conduct long range reconnaissance patrols, gather intelligence from concealed observation posts, raid enemy installations (especially supply depots), conduct road side ambushes and pursue and destroy enemy special forces units.

In wartime, an unspecified number of reservists assigned to Sissi battalions would deploy and operate as small groups up to company size. They are meant to stay behind and covertly operate against enemy forces in their area of responsibility even if regular friendly troops have been forced to retreat. Sissi battalions are part of Finnish Army local troops, unlike the jäger and armored brigades meant for operational use. Sissi units are considered as the elites of the Army conscripts, and many of the units, such as the Paratroopers or Border Jaegers, are formed of volunteers.

Wars between Russia and Finland have a long tradition of Finnish sissi warfare. Famous sissi leaders have included Pekka Vesainen (c. 1540—1627), Tapani Löfving (1689–1777, fought during the Greater Wrath), and Olli Tiainen (1770–1833, fought during the Finnish War).
