Perhaps no form of warfare has benefitted so greatly from a disaster as the amphibious attack. Following the disaster at Gallipoli, the art of invading from the sea was revolutionized, with specialized weapons, vehicles, and tactics. By the time the second world war rolled around, battles at Normandy, Sicily, Salerno, Guadalcanal, Iwo Jima, and Okinawa proved that amphibious warfare wasn't going anywhere.
While those events were milestones in this particular breed of warfare, the way it's done today is, if anything, more organized and specific. Take, for example, this joint landing exercise between marines from the US and South Korea. Now, it's worth noting that a couple of the key elements of an amphibious attack are absent here. We'd expect ships parked offshore pounding the beachhead ahead of the landing, along with both fixed-wing and rotary aircraft, like the A-10 Warthog and AH-1W SuperCobra, to be tearing over head and punishing any enemy foolish enough to poke their head above ground.
Still, it's an excellent example of the discipline and organization involved in an invasion from the sea. Check out the video, courtesy of the team at Sploid.
