AMPHIBIOUS TRACTORS

Marine amphibious tractors approach a beach during a training
excercise. Developed to deliver Marines over the coral reefs
of the Pacific islands, the vehicle was invented by Donald Roebling
in 1937 to rescue people lost in the Everglades. Known as the LVT
(Landing Vehicle, Tracked), several models were produced, with the
basic one being the Mark I Alligator (pictured). With a capacity of
20 troops or 4,500 pounds of cargo, it soon became a work-horse
during island-hopping landing operations.
