The M939 is a 5-ton 6×6 U.S. military heavy truck. The basic cargo versions were designed to transport a 10,000 pounds (4,500 kg) cargo load over all terrain in all weather.
While they may be right about some things- silverback gorillas can measure up to 1.7m and weigh about 200 kg, so they are giant- they do not run around killing everything in the forest. They eat fruits, leaves, stems and termites. They don't shatter tree trunks or lift cars, except in movies.
Small cars: smaller models, such as compact, micro or light passenger vehicles, typically weigh between 1,000kg to 1,300kg, with some even weighing under a tonne. Medium cars: mid-sized passenger cars can weigh between 1,400kg and 1,700kg, although some may be heavier.
