Bombardment of the forts started on 30 August, with KMK Battery three tasked with lowering Ouvrage Les Sarts (Fort Sarts) nevertheless it mistakenly shelled an interval fortification in entrance of Sarts. At Grodno, KMK Batteries 3, 5, and 6 weren't even absolutely emplaced when the fortress was evacuated on 3 September. On the second day of the battle, vapeezigaretten each of KMK Battery 7's M-Gerät guns have been destroyed by premature detonations and KMK Batteries 5 and 6 each lost an M-Gerät every to the same cause.

On 13 August, KMK Batteries three and 5 attacked with the siege guns from the north, shelling forts XIV, XV and XVI.

The final deployment of M-Gerät guns on the Eastern Front was in October 1915, when KMK Battery 6 was connected to the German eleventh Army because it invaded Serbia.

KMK Battery 6 took part in the bombardment of forts X, Xa, vapeezigaretten XI and XIa, opened on 30 March. In the ultimate two years of the warfare, KMK batteries that suffered losses of their big guns had them replaced with smaller-calibre weapons. Siege guns were held in reserve as "non-standing batteries" that would be mobilised in the occasion of war.

Küstenmörser (coastal mortar), refers to giant-calibre mortars designed to be used in coastal batteries in opposition to ironclad warships. When the German Army was reorganised in late 1918, only Battery 5 had M-Gerät guns, eliquidbestellen (https://www.eliquidbestellen.de) and schwere Küstenmörser (SKM) Battery 3 was assigned the remaining two Beta-M-Gerät guns.

The M-Gerät designed in 1911 as an iteration of earlier tremendous-heavy German siege guns meant to interrupt modern fortresses in France and Belgium and entered production in 1912. Test firing started in early 1914 and the gun was estimated to be finished by October 1914.

When the primary World War broke out, the two M-Gerät guns, still prototypes, had been sent to Liège, Belgium, and destroyed Forts Pontisse and Loncin.
