Ukraine

And they're not a bunch of country farm idiots fighting alongside western forces either. The high tech advanced weaponry is being operated by Ukrainians. Russian soldiers are discovering for the first time who they're actually fighting. They were told it was NATO forces and some Ukrainians. Turns out its Ukrainians with some NATO equipment. That itself must be kind of... Unsettling. It raises question for the Russian soldier about what's really going on. Entering the Kursk region was a huge shock to the world, but I don't think anyone realized the propaganda value of entering Putin's sphere of misinformation with truth.
