The Institute for the Study of War has produced nearly 60 maps on Russian airstrikes in Syria since they first began on September 30, 2015.
The first map appeared less than 24 hours after the Russians began strikes and they continue today as do the strikes despite a declared "cessation of hostilities" and an alleged Russian withdrawal.
These maps helped show the world that Russia's claims of striking "terrorists" were clearly not accurate as they repeatedly attacked mainstream opposition groups, particularly those working with the West.
When intentionally false maps were produced by the Russian Ministry of Defense to show where they claimed strikes were occurring -- and that they were striking ISIS -- ISW's maps and analysis showed these claims to be untrue.
