In 1887, Hiram Maxim demonstrated his machine-gun to the Germans and suitably impressed after a long period of trials with the Maxim, a limited number were purchased by the Deutsches Heer in 1895 and the Kaiserliche Marine in 1896. In service, these weapons were designated as the Maschinengewehr 99 (MG 99). Minor updates were made to the MG 99 which resulted in the Maschinengewehr 01 which was officially put into service in limited numbers in 1901 as the MG 01. The Deutsches Heer was still not completely satisfied with the MG 01 and so further refinements were developed by both Spandau Aresnal and Deutsche Waffen- und Munitionsfabriken (DWM), mainly to lighten the weapon in action. The distinctive sled mount for the machine-gun was much the same as with the early MG 99 except that the ability to affix travel wheels to the sled which was introduced with the MG 01 was removed in order to save weight. The new machine-gun, the MG 08, went into production at Spandau in 1908 and entered service with the Deutsches Heer the same year. The MG 08, in action, was by no means a lightweight weapon. The entire apparatus for the MG 08, called the Maschinengewehr-Gerät 08, included the machine-gun (with 4 liters of water in the cooling jacket), the sled mount (called the Schlitten 08), two extra barrels, and two extra toggle locks added up to 137 pounds not including the ammunition. The MG 08 itself made up 58 pounds of the total weight. The MG 08 was 46 inches long with a 28 inch long barrel. The MG 08 had a rate of fire of 300 to 350 rounds per minute and ammunition was fed into the gun in 250-round cloth belts. To increase the rate of fire, muzzle boosters were fitted to some MG 08 weapons (which appeared as a reverse conical addition on the end of the muzzle) which increased the rate of fire by some 45%. Such guns were designated as the MG 08 mit Rilckstorsverstärker S. The effective range of the MG 08 was 2,000 meters though it had a maximum range of 3,500 meters thanks to its 2,838 feet per second muzzle velocity (with booster). By August 1914, the Deutsches Heer had 4,114 MG 08s, 398 MG 01s, and 18 MG 99s in service.
The photograph, however, does not come from World War One. Instead, it likely comes from the early 1930s and the main clue to this is the gas masks this machine-gun crew is wearing. The gas mask appears to be the Gasmaske 30, also known as the S-Maske or “Schutzmaske“, as evidenced by the rubberized canvas and the shape of the metal snout. The Gasmaske 30 was introduced in 1930 and would remain the primary gas mask until the introduction of the Gasmaske 38 in 1938. The loader, and probably the gunner, don't appear to have the filter in place. Had they, it would have been screwed into the snout. The mounting, however, isn't the Schlitten 08, and instead, it is the lighter Dreifuss 16 tripod which was introduced in 1916. We can also tell this is a training exercise as a blank firing adapter has been fitted to the barrel. Around the loader's chest and back are the drag straps used to haul the weapon around and near his foot is a shovel that was carried in order to quickly improve their position.
As for the unit, this might be told on the Dreifuss 16 where what appears to be 2/J.R.9 is painted in white on the tripod. Thus, if accurate, the men would be from the 2nd. Bataillon, Jäger-Regiment 9. This unit can be traced back to August 1916 when it was formed in Galicia under the original unit name of Regiment Veith. It was originally under Infanterie-Regiment 199 (I.R.199) commanded by Major von Notz of the XX. Armee Korps. Jäger units were considered light infantry whose primary missions were skirmishing, reconnaissance, and sharpshooting. However, most of the of the Jäger-Regiments that existed in World War One were disbanded with the onset of the post-WW1 German military, the Reichswehr, which was limited to only 100,000 men. Still, the traditions of the Jäger-Regiments carried on into the infantry regiments created under the Reichswehr and by 1933, the usage of the term “Jäger“ would again reappear as Germany expanded the military. That said, the men could be from a different unit all together only that their equipment, in this case the MG 08, was from the disbanded J.R.9.
