It’s not a game, it’s the new US strategy. The US Marines and Army will operate highly survivable long range precision strike networks and integrated air defense systems along the first island chain. A mixture of advanced anti ship missiles, Precision Strike Missiles, cruise missiles, future intermediate range ballistic missiles, and hypersonic missiles. US submarines will also be operating forward.
The second island chain will host the much larger force of the US Navy and Air Force. They will operate out of the range of most Chinese ballistic missiles, providing long range strike from stealth aircraft and ships. JASSM-ER, JASSM-XR, Maritime Strike Tomahawk, LRASM, SM-6, and hypersonic missiles will feature prominently.
Remember, all the US has to do is deny China from achieving its objective. We don’t have to invade you. And Chinas merchant fleet will be at high risk as well.
