My knowledge of the CCF is relatively limited -I didn't join when they came recruiting, I was a suspicious little thirteen-year-old with very little inclination for drill that wasn't self-inflicted- and my brother is not available for grilling as he's off on a sleepover, but Wikipedia covers all manner of sins. According to it, all cadets start off learning to use a .22 Number 8 Rifle or L98A1 5.56 mm Cadet General Purpose rifle, the latter being like an SA80 only not semi or automatic loading, and later on the L86 LSW, the L85A2 rifle, and the L81 Cadet Target Rifle. She'd also know first aid, navigation and drill (according to little brother, there is lots of this and it is mind-numbingly dull) and, again according to Wikipedia- 'Army section cadets are able to specialise in various subjects such as signalling and infantry tactics, and are trained accordingly. The Army section also has "special to arm" courses, such as advanced weapons theory, Royal Signals training, and REME [Royal Electrical and Mechanical Engineers] courses. Royal Artillery Adventurous Training courses are often offered to cadets, usually through an Army Liaison Officer. These include parachuting and watersports training.' Liz is pretty keen on CCF- I leave it up to you and your plot as to what she's attended/specialised in, but it certainly wasn't REME.
