Drones film what they attack. Artillery and Infantry generally don't.
The Armenians have actually released multiple videos of what their artillery and infantry are doing, but with the Azeris refusing to acknowledge that they are taking casualties at all none of really know what kind of effect it is having.
The you tube video of the debacle on the hillside road that you posted twice here is from 27 September. Indeed the Armenians were the first to publicise a range of videos showing kills by artillery, ATGM and mines.
Another thing you posted here is from 3rd October. Your post only serves to emphasize the stunning disparity in losses between the opposing forces.
Do the math....
current Population of Nagorno Karabakh: around 150,000
Population of Armenia: around 2,965,000
Population of Azerbaijan: around 9,981,457
What kind of government of a population of only three milion can afford to sacrifice its soldiers the way they're doing?
