Actually that happened during Gulf War 1 (Desert Shield).  For a few weeks 
during that conflict, the US military had to pull its KWM-2As out of 
mothballs, to use in the Middle East at bases, due to the fact that the 
static electricity caused by the frequent sandstorms that area gets, was 
zapping out their microprocessor controlled radios.  So, until they could 
come up with some EMD/EMP hardened gear, they used the KWM-2As.
