AIM

The aim of this agreement is to standardize the nominal voltage of the
electrical systems of tactical land vehicles for practical purposes such
as:

     (a)  The ability of giving or receiving electrical power support on
          starting the engine when necessary;

     (b)  In the case of a vehicle combination truck trailer or a prime
          mover/semi-trailer from different member nations, the ability to
          supply the trailer or semi-trailer electrical power for its
          lighting.

     (c)  To acquire the interchangeability of vehicle electrical
          components of different makes or from different member nations
          in case of emergency.

NOTE:  The circuit characteristics, such as voltage drop, ripple, surges
and spikes are not specified in this STANAG.
