Had this experience in Oz 2 years ago. Went on a course with a CW4 helo pilot. No one knew what to call him or exactly what CW4 meant. So we asked. He was happy to go by first name basis with officers (no junior ranks on course). Out on the base no one saluted him, and h didn't get antsy. So New_WO1, i don't think you have a leg to stand on. Expecting a salute is like trying to get blood out of a rock. Do you feel better at night for being saluted? (i bet you do!!)
