on my section commanders course i said that i always wanted to be a porn star but my cocks too short and i'm shit in bed, so i ended up in the army! went down well with everyone but i would advise against it if its your initial interview
they put a sheet in front of you with a few headings like family, hobbies etc. So if you get stuck you can look at that to jog your memory. It's not so much about what you say, its how you say it which is more important. Be confident, stand up straight, look people in the eye and you will be fine!
On my Ice breaker they told us to just stand in the 'at ease' position. Just stuck to that, only thing that made me panic was delays reading the board, not talking and keeping everyone waiting while i thought of an answer!
It's ok though, everyone is in the same boat at the end of the day, and its not like you will get picked on if your a bit shy and nervous on your icebreaker!
My leg started shaking and I was doing a mini elvis impression! Ah well it gave us something to laugh about and produce a smile in the final interveiw!
Its generally a list of things to talk about (the same list will be on a board in the room where you do the icebreaker).
You - your name, where you live, who with etc.
Why you want to join the army.
First Job choice and why.
Hobbies, and what you do in your free time.
What you are doing in prep for the army.
Specify your run time and maximum number of heaves.
I think there were a few more points but I can't remember them at the mo!
Good luck mate, as Skitch says, just remember you're all in the same position, and its not that bad!
