Whether it’s Russian hostility on Europe’s eastern borders, Chinese attacks toward partners in the Pacific, or Iranian deception in the Middle East, the current solution has centered inside ubiquitous sensors to keep track of what’s happening and longer-range, faster-moving fires to attack where it stings. The Navy seeks more vessels with greater security, while a top Air Force general labeled the Army’s long-range fire plans “stupid,” claiming that his branch already has that addressed. The Marines have spent the last year abandoning tanks in order to become more flexible in their marine operations. While the Army is focusing on improved weapons, systems, and sensors, it is also investing heavily in armored vehicles. This includes armored troop carriers, robotic battle partners, and the tank, which is the foundation of the ground war. If the present Army budget for 2022 is authorized, those ambitious objectives will suffer a short-term setback.
