Geri,
Think of everything you have done in the mob in the last 10 - 15 years, write it down and then take it apart to nail down the skills / qualities used + required in said task. My point is that you will be gobsacked at what you have done ( especially on ops). Then get that onto paper and you wil have the start of a great CV. Also work on a CV and have a good effort ready to go for the CTW. It will get picked to peices, but that is only to your benifit as you will have a stroger CV when you leave.
Best of luck, PM if you need more gen.
