Obrona Narodowa (ON) - National Defense, was Polish volunteer territorial military formation, organized in 1937. It was supposed to help regular army in defence.*

During mobilization, Obrona Narodowa formed 83 battalions of different combat value, and different armament. They were worse equipped with machine guns and support weapons, than regular army, and often used older marks of armament, like Maxim wz. 08/15.*
Apart from standard 7.92mm Mausers, typical rifle was 8mm Berthier.*
Typical HMG was 8mm Hotchkiss wz.14, and, mostly in Silesian units, 7.92mm Maxim wz.08.*
