[note 1] A Kampfgruppe could range in size from a company to a corps, but the most common was an Abteilung (battalion)-sized formation.
Men trained in these methods were known in German as Sturmmann (literally "assault man" but usually translated as Stormtrooper), formed into companies of Sturmtruppen (Storm Troops).
With respect to their ad hoc nature and objective-oriented strategy, Finnish ski troops employed during the Soviet-Finnish Winter War of 1939-1940 could, in principle, be considered an equivalent to Kampfgruppen.
[2] In the Continuation War (1941–44), battlegroups (Finnish: taisteluosasto) were commonly used by Finns and were bigger, having infantry, artillery, and anti-tank units.
Famous examples include: A Panzerkampfgruppe was effectively the main striking force of a Panzer division.
During the Second World War, the Kampfgeschwader bomber units of Luftwaffe consisted of several Kampfgruppen, which, in terms of size, were somewhere between squadrons and groups of Anglo-American air forces.
