190k? Give a source. All I'm seeing is 70k Russians actually deployed inside Ukraine and a 25-30k combined forces of the DPR/LPRThe invasion force was 178K. They sent more soldiers after they captured Iraq in order to secure it.
Regardless, they were facing 1.3 million Iraqi soldiers then.
Russia is sending 190,000 troops which is the largest invasion force seen since WWII for a military of 200K.
