The Complete History of the Presidential State Car
Ground Force One Supplements the State Car
In addition to the state car, there is also Ground Force One, the code name for the armored black buses. These buses transport the Chief of State as well as other dignitaries. Ground Force One was introduced in August 2011. Prior to this, rented buses were part of the motorcade and had retrofitted communications if necessary. Interestingly, the original Ground Force One vehicles were first used by Obama during his campaign. Given his positive experience and faith in these vehicles, it was natural to make them an official mode of transport.
