Let's give you more useful info than the Defense Minister's resignation: David Torosyan

David Torosyan, president of the NGO "In the Name of the Armenian Soldier," wrote on his Facebook page: "Let me provide you with more useful information than the Defense Minister's resignation. There are talks in various places that at night 'the sky was lit up with gunfire, it definitely isn't automatic rifle fire.' Friends, those are ordinary gunfire from standard assault rifles (AK), machine guns (ПК), or light machine guns (РПК) with tracer rounds (трассирующий). You can't see a mortar shell; at most, you'll hear a whistle-like sound for about 3 seconds before the explosion. This is a brief guide on how to tell what kind of weaponry is being used."
