Every report I've seen says that not only did they meet the quota, they also got around 70k volunteers. Russia has over a 100 million people, it's absurd that anybody would think they couldn't scrape 300k troops.

Also, Russian mobilization cut off was at the age 45, while Ukraine just announced a mobilization of anybody under 60. That does give a hint regarding who's hurting more for troops.

Meanwhile, literally millions of people have fled Ukraine already, and you seriously think Ukrainian troops are better equipped with their hodge podge of donated weapons from NATO inventories?
