The Mark VIII (also referred to as Liberty or International) is an early tank design used by the United States Armed Forces during the early Interbellum period.
Retaining many of the features of the Mark One through Five tank series, the Mark Eight nonetheless introduced a number of changes to the design, the most important of which was the introduction of compartmentalization, separating the working engine from the crew, shielding them against noise, fumes, and heat. Otherwise, it was a typical First World War line tank: Huge, slow - top speed was just 5.25 mph (8 km/h) - and poorly armored, though with a pair of 57mm guns it could project excellent firepower. It was originally intended for the 1919 offensive against the Central Powers, with initial production runs fielded in Europe as soon as possible, but delays caused it to enter service after the capitulation of the Central Powers. Ultimately, it failed to make an impression and all existing tanks were scrapped by 1940.
- The mural is incorrect in two ways: First, it depicts a turreted Mark VIII, second, it shows it as fighting on the frontlines.
The Mark V tank appears in the mural at the Museum of Freedom in Fallout 4.
