pile , i think you find its down to the "childrens act" and also down the "sue you , sue me , sue everybody" culture, so unfortunatly most instructor wil have to bear that in mind and follow procedures otherwise they will be personally liable ending up out of pocket . shame really as many of the activities would have been fun .
i would have thought paintballing would be a useful way of learning combat techniques and whats it really like to operate under fire while having fun at the same time , but it would have to be an activity outside of the Army Cadet Force ( private arrangment) ,incidently how many of you do paintballing, i enjoyed it myself ( it hurts sometimes tho , lol )
