I have been puzzling over this.  The JARGON file (as stored on ITS)
says:

  GUN [from the GUN command on ITS] v. To forcibly terminate a program
     or job (computer, not career).  "Some idiot left a background
     process running soaking up half the cycles, so I gunned it."

But there is no straightforward GUN command on ITS.  There is no TS GUN
program, and no GUN command in DDT.  There is a GUN command in LOCK,
which is used to kill an entire user job tree.  LOCK also has a command
to bring the system down: DOWN a.k.a KILL.
