I did know an Armourer Corporal that was fully qualified as a Music teacher, and a very good musician, naturally he applied to join as a Musician and not having any places the careers disinformation service told him, " join as an armourer and remuster to musician" this he did then found out the porky pies he had been told....... hence one disgruntled Armourer.... as one cannot go down in trade groups, just up.
One does hope things have at least moved on from that.
