I'm an instructor. I really wish I'd got my own kids involved but I never really thought about it at the time despite being ex-forces
You have different levels of achievement in the syllabus and move up as you pass each star level. So, basic, one star, two star, three star, four star, master cadet. You can also be promoted in rank from cadet up to cadet Regimental Sergeant Major. Lots of achievement to be had and there is DOE as well, which doesn't cost you extra.
Subjects are: military knowledge, adventure training, community engagement, communication information systems, drill and turnout, first aid, fieldcraft, navigation, PT, skill at arms, shooting, expedition.
Usually one evening a week, at a small cost (50p at ours) and a shade under £15 for a weekend away ( includes food, those in free school meals pay less). One week annual camp is £80 or so. Adventure training weeks are generally a bit more. There are additional courses and qualifications to be had too if wanted. Uniform (except boots) is provided, most kit is provided as required.
It's actually really, really good. The kids get loads out of it and ours seems to love it. It's learning that's different to school, there's potential to take on responsibility and the maturity and respect for others builds naturally. I've witnessed some right little sods turn round into proper good people which was the founders aim really.
Our motto is inspire to achieve and it's actually really accurate in what we do
October there's a national open week kind of thing going on so you should be able to have a proper look at things.
