Remember the tanks that had the marking painted on them as Z ( zed in English or zee in American English).
There is no Q or ( cue) sound in Russian Cyrillic , no way to use it.
The Russian keyboard is not QWERTY it is JCUKEN.
Take a look at the letter placement and see which letter takes up the place of a Q.
Yes it’s a unique Russian letter that is written as a backwards Z.
Just another coincidence to add to the list.
They marked their tanks with a Q👍

I’m referencing the post 1917 Russian Alphabet . The letter is written as a mirrored Z . It is not a direct replacement for Q in translation as the Russian Cyrillic doesn’t use the Cue or qwu sound.
The letter is a low ranking consonant in the usage table and on the standardised Russian Keyboard it’s placement is at the same place as a QWERTY Q is found.
Variations in Cyrillic exist across the region but the letter I’m referencing as Q replacement on the keyboard consistently is placed there in ALL regional languages across the Caucasus.
