What is "shershen"

The Shershen is a Belarusian third generation anti-tank guided missile (ATGM), designed to defeat modern armored vehicles, protected objects (such as bunkers, pillboxes, earth-and-timber emplacements) and low-speed low-altitude targets (helicopters, UAVs). Being a logical extension of the ATGM "Skif", "Shershen" beats it in technologies level, as well as implements engineering solutions that are unique among the others.
