  "textContent": "An airport rescue fire fighting vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, an energy storage device, a water tank, a water turret, an electromechanical transmission configured to drive at least one of the front axle or the rear axle, with the electromechanical transmission including a plurality of electric motors, a gear train coupling the plurality of electric motors, and a power-take-off, a pump system configured to pump water from the water tank to the water turret, and a hydrostatic drive. The hydrostatic drive includes a hydrostatic pump coupled to the power-take-off, and a hydrostatic motor fluidly coupled to the hydrostatic pump, with the hydrostatic motor coupled to the pump system. The hydrostatic pump is driven with the power-take-off to pump hydraulic fluid to the hydrostatic motor to drive the pump system.",
