The old duece, as well as the MLVW (and the US M35) only use the air as an assist. You will still have brakes despite the loss of air. That is why you do not need an air brake license to operate them. However, hook up the 1-1/2 ton trailer and you now need the air brake license. If you lose the air system, you will not have any braking on the trailers.

At least that's how I have always understood it.
