          not all inclusive).

          Desensitization
          Desensitization entails reducing or extinguishing the OpK9’s
          adverse behavioral response to a provoking stimulus through
          graduated, repeated exposures.  The technique requires a sig-
                                  3
          nificant amount of time to perform successfully and, therefore,
          is often not suitable to pursue during a short-term mission or
          deployment. Instead, attempt to desensitize the OpK9 to any
          anticipated environmental or social stressor(s) they may en-
          counter down range before deployment.

          Behavior Modification
          Modify behavior to the provocative stimuli by countercondi-
          tioning and positive reinforcement.  Counterconditioning in-
                                      3
          volves attempting to evoke a different, but favorable, response
          in the presence of the provoking stimuli by having the OpK9
          engage in a competitive behavior or activity. Positive reinforce-
          ment encourages or supports the wanted behavior with a pos-
          itive action, such as verbal encouragement, physical affection,
          and/or a toy or food reward. For instance, in attempting to
          stop self-inflicted barbering, consider providing verbal encour-
          agement or a small food reward when the OpK9 appears re-
          laxed and is not barbering while in the presence of the stressor   Topical Therapy
