Feldgruppen
Feldgruppe is a German military term used to describe a small field formation, typically formed for field operations and tasks requiring a compact, flexible unit. The exact size and composition varied by period, branch, and mission, but a Feldgruppe generally consisted of a small number of infantry personnel and could be augmented with specialists such as engineers, radio operators, or light weapon support. It was not a fixed unit with a single standard table of organization; rather, it functioned as an ad hoc detachment drawn from a larger unit to carry out specific tasks.
The roles of a Feldgruppe included reconnaissance, security duties, and light assault or raiding operations. Such
Historical usage of the term is most commonly associated with German forces of the World War II
