The photos below are showing improvised artillery and firearms from the times of the Artsakh Liberation War. These weapons were used by the forces of Armenian military organizations. The latter would become the foundation for the Artsakh Defense Army.
It was with these weapons that the self-defense units went on sabotage against the USSR Ministry of Internal Affairs and fought against the special forces of the Azerbaijani SSR at the initial stage of the conflict (1988-1991).
In the second photo, you can also see Monte Melkonyan, an Armenian volunteer from the United States.
