A land mine simulator includes a housing having an opening formed in one end thereof. A plate movably supported in the housing's opening has a first face exposed to a surrounding environment and a second face exposed to an interior region of the housing. A non-compressible fluid-filled reservoir in the housing includes a flexible diaphragm opposing and spaced apart from the second face of the plate. Plungers are between each of the second face of the plate and the diaphragm. Each of one or more air spring in the housing includes a cylinder having a movable piston sealed therein with a first side of the piston in fluid communication with the reservoir's fluid and a second side of the piston in fluid communication with a pressurized volume of gas within the cylinder. A pressure sensor is provided in communication with the fluid in the reservoir.
