This article may be good paying attention to the new Russian armor protection. But it has a lot of lapses.
Just one. Russia didn’t install it on her tanks WIDELY before simply because there were NO threats around from any enemy forces which might make her purpose really needed.
Until now in this war. So let us see how it will work in real war. Actually they test her against tow2 and other staff they captured from ukies. The article says she withstood tests.
Every potential opponent that Russia had has had tandem warheads or top attack since the 1980s. All this was universal from the 1990s. The Chinese certainly have all this.
Javelin and advanced Tow or Spike or Stugna were not surprises.
Unless Russia planned only to fight guerrillas in Dagestan.
