Modern tanks are versatile mobile land weapons platforms whose main armament is a large-calibertank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, and thus be more flexibly positioned at advantageous locations on the battlefield. These features enable the tank to perform in a variety of intense combat situations, simultaneously both offensively (with direct fire from their powerful main gun) and defensively (as fire support and defilade for friendly troops due to the near invulnerability to common infantry small arms and good resistance against heavier weapons, although anti-tank weapons used in 2022, some of them man-portable, have demonstrated the ability to destroy older generations of tanks with single shots),[disputed – discuss] all while maintaining the mobility needed to exploit changing tactical situations. Fully integrating tanks into modern military forces spawned a new era of combat, armoured warfare. (Full article...)

The SS America was an ocean liner built in 1940 for the United States Lines. She carried many names in the 54 years between her construction and her 1994 wrecking, as she served as the SSAmerica (carrying this name three different times during her career), the USS West Point, the SS Australis, the SS Italis, the SS Noga, the SS Alferdoss, and the SS American Star. She served most notably in passenger service as the SS America, and as the Greek-flagged SS Australis for Chandris. In 1941, she carried two Nazi spies from the Duquesne Spy Ring in her crew: Erwin Wilhelm Siegler and Franz Joseph Stigler. Both men were charged by the FBI with espionage and sentenced to 10 years and 16 years' imprisonment, respectively.
