World War ‘Z’? Russian tanks with mysterious marking enter Ukraine

Nothing to really speculate here. The article says it all. All military’s use similar markings in time of conflict when warring parties have similar looking vehicles to avoid confusion and friendly fire etc.

So some enterprising Ukrainian Solders paint Z's on their vehicles or just kill everything with a Z on it, it cuts both ways.

Not a good situation. Too eerily close to General Z as in Zod and his ultimatum.
