According to statistics from the oryx website, a foreign open-source intelligence organization, Russia has lost over 1,500 tanks in the Russia-Ukraine War, including several cutting-edge T-90M tanks.
Not long ago, a T-90M was destroyed. It is said that a Swedish AT4 rocket launcher hit it in a weak area. In modern warfare, attacks from all directions with 360° and no dead ends made the former king of land warfare hard to defend.
