Glider infantry (also referred to as Airlanding infantry esp. in British usage) was a type of airborne infantry in which soldiers and their equipment were inserted into enemy controlled territory via military glider rather than parachute. Initially developed in the late 1930s by Germany, glider infantry units were used extensively during World War II but are no longer used by any modern military.
