The Navy Land Plane Jastas of the Naval Air Service were relatively small and quite elite compared to the Navy Sea Plane arm. These squadrons, which flew in Flanders alongside Army Jastas, produced some of the best fighter pilots of the war. These men were often among those with the highest scores of planes shot down. This militärpaß was to an enlisted man who served in one of these jastas, most likely as a ground crewman. This man first entered the Navy in June 1917 and was initially assigned to II. Matrosen Division. He survived the war and entries from as late as 1920 appear in the militärpaß. It is a very difficult-to-find Militärpaß.
