In warfare the advantage of the glider over the airplane is its more silent arrival at an objective. Using the DFS 230 Glider, the Germans landed a few glider-borne troops at the Albert Canal and Fort Eben Emael in 1940. Such troops were previously in readiness during the invasion of Norway, but whether they were actually flown to combat in Norway is debatable. After Belgium fell, the Germans pushed their glider-training program. In January 1941 the partly glider-borne unit, 1st Assault Regiment (Sturmregiment 1), was created; and the corresponding towing unit of Ju-52's, the 1st Air-Landing Group (Luftlandegeschwader 1), was probably created about the same time. Both of these organizations saw service at Corinth and in Crete. The father of German military glider training is said to have been Brigadier General Ramcke, who in mid-1942 was still a leading figure in German air-borne development.
