LCAC hovercraft
The air cushioned landing craft, or fully amphibious landing craft, is a more modern variation on the amphibious landing boat. These craft are based on small to mid sized multi-purpose hovercraft, also known as 'over the beach' ('OTB') craft. This allows troops and material to access more than 70% of the world's coastline, while only approximately 15% of that coastline is available to conventional landing craft. Typical barriers to conventional landing craft are soft sandy beaches, marshes, swampland, and loose surfaces. Air cushion technology has vastly increased the landing capability of the craft, providing greater speed and flexibility over traditional landing craft. Like the mechanized landing craft, they are usually equipped with mounted machine guns, although they also support grenade launchers and heavy weapons. These vehicles are commonly used in the United States Navy, which first received them in 1984, the Russian Navy, and some other modern fighting forces, such as the United Kingdom's Royal Navy. Forces that may use the LCAC may include The Royal Marines. (from Wikipedia)
