Tanks have a difficult task ahead of them. They're built to mount offensive weaponry on a mobile platform while also offering defensive protection for the crew, and they won't break in the process. A tank is usually an assembly of complex technology, systems, and hardware to order to meet those criteria. At first glance, it's not always clear how some of these components work or what their purpose is. The bulge in the barrel observed on most modern tanks with high caliber weapons is a widely misunderstood aspect of a tank. A bore evacuator, also known as a fume extractor, is this bulge.
