On a pleasant detachment with 115 Squadron, as the Paras came back to Brize from the victory down south, there was a bearded Nav on one of my joy rides in the Andover. I was fascinated by his full set, as I had never seen one on my time in the UAS. Having been told you had to have a medical reason to wear one, I wondered what was up with said Nav. He looked the picture of health to me. Alas he decided I wasn't worth acknowledging and I never found out why he was sporting the facial hair.
