How were drones used there?

At the start of the war, Azerbaijan sent slow-flying Soviet-era aircraft that had been converted to drones to bait Armenian air defense units—tempting them to fire and expose their location, at which point they could be hit by TB2s or Israeli-made kamikaze drones. Having achieved aerial dominance, Azerbaijani drones then devastated Armenian forces, destroying at least 106 Armenian tanks, 146 artillery pieces, and scores of other vehicles. After six weeks of fighting, the Armenians had no choice but to sign a humiliating truce. Nagorno-Karabakh, said Malcolm Davis of the Australian Strategic Policy Institute, was “a potential game changer for land warfare.”
