Landing Vehicle Tracked

         In 1933 it became apparent to many people that another war with Europe was going to be inevitable because of the power hungry dictators across the world.  With this threat in mind, the United States Marine Corps needed to think of a new vehicle that can be used to their advantage.  Lucky for them,  there was a  vehicle named the Alligator.  The Alligator was originally designed by Donald Roebling in 1935.  The purpose was to rescue civilians who were not accessible by land or by boat.  The solution was to come up with something that serves as both land transportation and water.  The United States Marine Corps adopted this idea with Roebling's help and created a version that can stand up to the forces that occur in the sea.  It also had to be able to carry men or other equipment needed so it was necessary for it to be big and spacious.  These were problems that Roebling was quickly able to solve and get the final product out just two years later where he produced about one hundred LVT.

         The LVT worked by having treads on the bottom because they are water tight and roll easily.  However, they need to be greased regularly to unsure proper rotation.  Once it is in the water, they use water propulsion jets to push themselves forward at a very monotonous pace of about 5 mph.  

         Thanks to the invention of the LVT we have amphibious cars like the duck car that always drives around outside of Giants games with passengers and give them a nice tour of the inner bay.
