Isn't Stalin rumored to have said, "There's a certain quality in quantity" in response to criticism that quality beats quantity? I think the quote is one of those unproven maybe-it-happened-but-we-have-no-solid-evidence things, but it seems to sum up the Russian approach to tanks and troops in WWII well enough, and from stories I've read, seems to be reflect their approach in the spy world as well. They are immensely practical.
