When I was a youngster in the Militia 30 years ago a Crew Jacket was a much sought after item. I was both a Recce and CP tech in the Artillery and they were fantastic if you could get one. Warm, and the pencil/china marker storage was perfect. I never did acquire one, but I suppose there has always been a niche for other branch items for outsiders. Hell, when I was with 1CMBG everyone had a Norwegian sweater, American Rain gear, Ranger Blanket and Danner boots if you could fit yourself out to name a few things. Maybe the MP fancied himself as Worthy or Rommel.
