Your 4398 Military Model is five inches longer and the Heavy Duty description probably refers to the stronger than normal transom clamp and single tube joining the powerhead to the gearcase. Civilian versions had separate exhaust and driveshaft tubes making running in reverse impossible. Air-Borne Reverse could refer to the steering wheel which goes around the powerhead making it easy to spin the motor for reverse thrust.
