NDW - I trust you've never experienced the RAF stores system?
1. Stores are for storing. If they gave stuff out they'd be 'Issues'
2. You can't have one because someone might need it. (I have had this happen to me, just before I was going on an exercise)
3. You're not entitled to it (happened to a mate who is a Navigator. He wanted a new blue Nav bag because the handles had come off. He was told by the rather rude stores person that he wasn't allowed a NAV BAG because he wasn't a pilot or an AEO. Work that one out)
4. No. Just no. (I asked for a new Ops Black Holdall because mine had split down a seam. I was catagorically told by the Crystal Ball that I couldn't have one as 'Nobody from this base is being deployed on Ops'. I wish I had that insight.)
The bottom line is you probably won't get one because these are specialist controlled items that go on an issue card. The only uncontrolled flying clothing/equipment you can get now are underwear (socks and thermals). So it's eBay or nowt!
And to be fair - most RAF guys use the civvie equivalents anyway! They are very bulky items and i'd rather use a Bulldog clip for my TAPs or a small folder for any gen.
