I don’t know who this guy is, but this is clearly a joke, no? It’s just a funny spurious correlation.

“i only use 4chan”

This is me, I have had the same thing for breakfast every day for the last 5? maybe 6 years.

I don’t not believe this is a thing, I’m mainly bewildered at how I managed to never hear of this at all until now. Apparently I don’t hang out in the right parts of the internet to have seen this, from my recollection the first 6 months of the war was mainly people adding the Ukraine flag to their usernames and spamming it everywhere, plus some grainy footage on r/CrazyFuckingVideos etc.

This is the first I’ve ever heard of Zs being used on Russian vehicles. I’ve never spent long enough examining any of the war footage in detail to go like “oh there’s a little letter Z painted on that tank”, at most I might think “the tank is painted with some markings to identify it” and move on to whatever the actual focus of the picture was.
