Guns of Krepost Sveaborg

 Weaponry of infantry

A Russian infantry solder had a 7.62 mm rifle, model 1891 as a personal weaponry. Officers and under officers had also the Nagant revolver, model 1895.

Machine guns belong to heavier weaponry. First Maxim machine guns, model 1905, were ordered from Germany. They were modified to use Russian 7.62 rifle bullets. First models were equipped with a high carriage, big wheels and large armored shield. The Maxim machine gun, model 1910, were the most common gun in the land front of Krepost Sveaborg. This newer model has carriage with smaller wheels, but had also feet so the gun could be lifted to the higher position.

Beside the Maxim machine guns there were also Colt-Browning and Vickers machine guns in the Russian fortress army. First light infantry mortars were made in Finnish metal industry factories. Infantry used also many types of small caliber cannons. Muzzle loading bronze mortars to anti-aircraft guns were found from land front storage areas after the war.
