Humvee M1025

The HMMWV (High Mobility Multipurpose Wheeled Vehicle) M1025, or Humvee, is a military light armored utility vehicle which is owned by Rika Minami. The Humvee is driven by Shizuka Marikawa as she and the rest of the group escape from Rika's house, and it serves as their primary means of transportation until they reach the Takagi Estate. In the Manga, the EMP disables the Humvee due to lack of anti-EMP measures (do to lack of funding). However, in the Anime, the Humvee is triple copper plated and therefore EMP proof. The Humvee is shown banged up and most likely wrecked as Takashi's group enters the shopping town.

Trivia
The HMMWV M1025 used in the series is equipped with a deep water fording kit that allows it to be submerged up to 60 inches in water.
