Mate,
Sorry to hear about your situation. I went through it a few years back. Don't think being a SNCO will make things better. Firstly there are no garages available to SNCOs (at least not at my unit- and thats the big one in carterton!) So you have to make do with storage rooms and no help from the mess or the SWO. I personally think this is a disgrace as singly airmen have access to garages and having earned the higher rank, the perks have dissapeared with it. Sorry to rant but it sucks. Especially as like you I had years worth of stuff. Bite the bullet and store it in a warehouse or get a garage if you can and don't let go! Good luck fella
