The 21st century brought new rules to military engineering. A growing spectrum of threats forced designers to increase protection across every class of combat vehicle. Weight had to rise, but crew safety became the priority.

Turbojet engines have long been a cornerstone of modern aviation. Today, let’s dive into how these powerplants work.

In 1961, Japan’s Self-Defense Forces adopted the Type 61 tank. Compared with contemporary American or Soviet designs, it looked outdated almost from the moment it appeared. Yet despite its obvious shortcomings, it remained in service for decades, simply because it was exactly what the country needed at the time.

The British Matilda rarely takes center stage in wartime chronicles. Yet crews across the Commonwealth fought in these slow, peculiar tanks from the early years of World War II to its very end. When Vickers engineers designed it, they drew heavily on lessons from the long-gone First World War. Yet remarkably, they still nailed it. The Matilda turned out to be relevant even as the nature of warfare evolved dramatically.

Meet one of December’s headline additions: the Terminator fire support vehicle. In-game, it comes in two versions: the tech-tree BMPT and the premium BMPT-72.

As early as the beginning of the 1940s, aircraft designers understood that the future belonged to jet propulsion. In practice, though, that potential took time to unlock. Early engines were temperamental and unreliable, and their thrust was barely enough to compete with the best piston powerplants of the day. Even so, leadership kept pushing this new kind of aviation forward.
