A native of Rivne in Western Ukraine, Serhij Markov, an invalid and retired engineer, developed a silencer for submachine guns that quashes the noise and flame, Ukrinform reports June 10.
As the war in Donbas broke out, Markov began to modernize the existing silencer. The inventor says his silencer is unique. He had it patented.
His silencer is already in use in the Ukrainian army in Donbas.
