200 Russian Military were killed by the United States in Syria!!
The battle happened Feb. 7, 2018 when Syria’s dictator Bashar Al Assad, backed by Russian mercenaries from a dark Russian company called Wagner, a private military company under the direct control of the Kremlin, whose soldiers fight on the side of the Assad government. Wagner fought against Ukraine in Donbass. Wagner launched an attack on U.S. forces and members of the U.S.-backed Syrian Democratic Forces, a predominantly Kurdish group, in eastern Syria. The opposing force consisted of tanks and heavy artillery.
After a massive American counter-attack involving air and artillery strikes beat back the opposing troops, reports emerged afterwards suggesting that as many as 200 Russians had died in the engagement, which you can read in more detail here, here and here.
