A load assistance device in which the soldier moves the device, not vice versa, includes a load receptor for receiving load from the mass a boot clamp for transmitting the load to the users boot and a linkage connected between the load receptor and the boot clamp, the linkage having an actuated condition in which the linkage transmits load downward from the load receptor into the boot clamp and having an unactuated condition in which the linkage does not transmit load downward from the load receptor into the boot clamp. At least one sensor senses the users stride. A computer is responsive to the sensor for controlling movement of the linkage between the actuated and unactuated conditions. The linkage is moved into the actuated condition upon sensing of the commencement of the stance phase of the users stride and is moved into the unactuated condition in response to sensing of the heel lift phase of the users stride.
