First rule: if he/she's got stripes on their sleeve, never call him/her "Sir" or "Ma'am". Use "corp", "sarge" or "flight", or you'll get a bollocking "Don't call me 'Sir', I
work for a living"
Second rule: Your Steyr is a 'rifle', not a 'gun'
Third rule: Never, ever tell the recruits too much. The glorious uncertainty of it all is part of the pressure cooking which removes all traces of civilianism and turns out the finely-honed military machines which are today's Air Force.
Damn. Told you too much. Now I'll have to kill you
Oh, and if your profile is accurate, you'll be 'Grandma' or at least 'Mum' not only to the other recruits but some of the instructors too
