Both your numbers are untrue.

Russia has more than 200,000 forces in Ukraine right now. Lets not pretend that DPR/LPR "separatists" are anything but Russian soldiers in unmarked uniforms. Remember the "separatists" involved in shooting down the Dutch plane in 2014 all turned out to be Russian soldiers.

The total number of combat ready soldiers in Russia's army is also far less than one million. More like 400k-500k.
