A ratchet platform is vertically adjustable and supports a soldier standing thereupon. The ratchet platform has a platform upper assembly having a platform and a ratchet. The ratchet has a platform riser tube and a ratchet rail. The ratchet platform also has a platform lower assembly having a support column and a platform base. An end of the ratchet is proximate the platform and an opposing end of the ratchet is disposed within an interior of the support column. The ratchet platform has a platform upper assembly actuator having a pedal sub-assembly and an upper linkage. Actuation of the upper linkage actuates the ratchet to adjust the height of the ratchet platform. The ratchet platform also has a base plate secured to the vehicle floor. The ratchet platform has a seat plate which provides support to the platform upper assembly, the platform lower assembly, and an energy attenuation system.
