In the alternative timeline, where the Cold War ended with the triumph of the Nationalists. One last battle has be fought. Europe is running out of any possible energy resources, the industry is stagnating and European Union's greatest foe - the union of Eastern European rogue states known as the "Intermarum" has issued an economic blockade on its mighty western neighbor. Too long we have tolerated these hordes making illegal genetic experiments on people and polluting our holy continent with the wastes of their nuclear production. Too long they have polluted the North Pole and refused to disarm. It's time, commander. It's time, commander, to break through their failed regime with our legions of steel and fire.
"Like knights of the past we penetrate the lines of the enemy under the cover of unbreakable iron and steel - our Leopard tank even in it's most archaic modification sees no match on the enemy side. Welcome aboard, tanker!"
I like your render style, very professional looking :P
