Scenario to be Simulated: 50 km from the forward supply point to the using unit described as follows: The typical mission/field transport scenario starts at the port staging area (PSA). The movement prior to this point would include transport by commercial common carrier, military long-range aircraft, ship, and/or railroad. This movement would occur over improved road surfaces or in platforms which have been proven to impose significantly lower vibration levels than those vehicles used for transport from the port staging area to the using unit. The commercial common-carrier platform environment would be significant only if no other ground transportation is to occur after arrival at the port staging area. The typical scenario has established that 50 km of transport are expected between forward supply point to the using unit. This transport is in two-wheeled trailers. The road surfaces will be paved, secondary, and cross-country.
