It was repeatedly defeated by the Germans and suffered extremely  high casualties.

Explanation:

Russia was known to be the world largest army. It has great source of manpower in the army that it became overconfident to win the war. After the attack on the Archduke Ferdinand of  Austria Hungary, Germans became hostile to Russia. Russia attacked Germany. The truth is that Russia had to give up because of the less infrastructural and road transport facilities were lacking which made Russia difficult to deploy its soldiers in major fronts.

The military strength was massive but Germans  knew the exact weakness of  the Russian military. Also the Tsarists regime in Russia was considered to be a massive failure by the Russians which arose internal conflicts and hence Russia was easily defeated in WWI.
