There's plenty of threads on this already, but here's the idea:

• Actions
  • Set Variable Position1 = (Position of (Triggering unit))
  • Set Variable ClosestUnit = No unit
  • Set Variable ClosestDistance = 99999.00
  • Set Variable ClosestGroup = (Units that are allied with Owner of (Triggering unit) excluding (Triggering unit), Dead units, etc)
  • Unit Group - Pick every unit in ClosestGroup and do Actions
    • Loop - Actions
      • Set Variabe Position2 = (Position of (Picked unit))
      • Set Variable CurrentDistance = (Distance between Position 1 and Position2)
      • If all conditions are true then do (Actions)
        • If - Conditions
          • CurrentDistance Less than ClosestDistance
        • Then - Actions
          • Set Variable ClosestUnit = (Picked unit)
          • Set Variable ClosestDistance = CurrentDistance
        • Else - Actions
  • Unit - Kill ClosestUnit <-- just an example

After the Loop is completely finished you will have your ClosestUnit. Don't forget to clean up the memory leaks.
