When I was younger (7) I use to play world of tanks with my dad as he found it very nostalgic and one of the main tanks we used was a soviet Churchill which was available on U.S.S.R branch, my dad being a really old part Russian man said It was named in honor of the prime minister of England at the time out of respect . Only when I got older I learned it was a tank of British origins and realize I was fed a patriotic lie, How the hell did it end up in the soviet hands.
Hello, here is a post from a couple of years ago by /u/iHistorian that looks at the scale of British military aid shipped to Russia, including a significant number of tanks that saw use in the defence of Moscow.
