Ya'Allah, the armenians are getting smashed! I will update with new maps ASAP.
Several important supply lines cut. The "capital" of Karabag is open now.
This would allow Azerbaijan to declare war on Armenia, and capture Armenian land. Azerbaijan is capable of it and is probably hoping for Armenia to do something stupid. Also, in such a scenario, Turkey will become more involved.
The same source which said the OSAs had been destroyed. the sum of 12 was divided between OSA and Buks. However, no evidence for the Buks has been provided yet.
They officially announced to have destroyed Buk's as well. As for the S-300, it is in the inventory of Armenia. Armenia is not officially involved in the war.
