But it hasn't captured any land. I don't think that Azerbaijan even planned for this invasion. The way they have lost men seems that they were manipulated by the Turks to invade and take nagorno karabakh. Without the drones the performance of the Azeris have been lacking whether it is to infantry or armoured. The armenians have been able to hold them without much out side help.
Azerbaijan is winning the war. The amount of equipments lost by pro Armenian militants and Armanian military is huge and it cannot be replaced easily. They do not have enough man power to replace personal loss either. Total population of nagorno karabakh is just 1.5 Lakhs. Losses are mounting and it's not sustainable.
Azarbaijani drones are clearing entire battle fields. If the war last for 1 month or more, Azarbaijan can easily capture atleast half of nagorno karabakh.
