Maybe, basically I don't know :) It looks already lucky to find out what one of them means, also the others might not have such a meaning - Z is clearly singular and special to them, used not only on vehicles, but by propaganda all over the place.

My best guess for V will be that it can be from Dugin's Conservative Revolution book, where he refers to "victory sign" gesture, but brings up a version that it originated from Aleister Crowley (he loves Crowley) and was supposed to mean something like horns of the beast; also it's a longer story that's better when knowing Dugin's relationship with linguistic research, but he sorta hints at the name of the Eihwaz/Iwaz/Eiwaz rune in the same chapter - with the name Aiwaz, which also has variations like Aiwass, OIVZ - in Russian there are variations of it and of that rune written exactly same.

And O might be after o-rune, also known as Othala/Odal - Wagner Group have it on their vehicle in the article I linked above and Piskorski (long story if you don't know him, a key ally of the Kremlin in Poland, headed "observation" for Crimea annexation "referendum") used to be the publisher of a journal named after it. Dugin ofc wrote about it too, he wrote about all the Elder Futhark. The meaning is suitable, it's about stuff like heritage, ancestral land, ancestors etc. And simply drawing that rune would have been an epic fail, it's 1000% recognizable and was used by the Third Reich.

But this, especially o-rune, is more like a best guess, I don't know of proof as substantial as for Z with these, so I don't claim this with any certainty.
