Hier in englischer Sprache, aber ganz einfach zu verstehen:
"Now military experts have claimed that these letters have been written according to the respective areas of the Russian army. This identifies the trains to which command they belong to."
Danach:
English letters written on vehicles - What do these letters mean
Z - Eastern Military District
Z in the box (Z in einem Quadrat) - Russian army stationed in Crimea
O - Russian army stationed in Belarus
V - Russian Naval Infantry
X - Kadyrov Chechnya
A - Alpha Ground Special Forces

Wenn man nach dem Z die restlichen Buchstaben und deren Verwendung ebenfalls als "Unterstützung eines Angriffskriegs werten will, dann wird es lustig.
Paranoides Klima, oder?
