IMHO, this thing is scary (Who on God's Green Earth would give this to South Korea?). AIFF (Artificial Identification Friend or Foe) is hard to program. You have to tell it certain features to look for, and us humans (last time I check anyway) are significantly different person to person. It'd only make sense to put that monstrosity near the DMZ because anybody who's trying to cross that thing either has an extremely accurate WMD (Icarus anybody?) that can take out the 100-mile(?) long minefield that makes up the DMZ, or an IQ barely above 2.5.
IMHO, that thing should be taken apart until we can get a decent AIFF algorithm.
