Used to have something, but fcuk knows where it has gone, but basically said, "keep it simple, in black & white with minimum fancy stuff" or it becomes death by power point. Have to disagree with statement as I have seen some tremendous power point presentations, which have been entertaining as well as putting the lesson across.
There is a guide that is produced by the design studio at Upavon. Best contact to get a copy would be one of the staff at Methods Section, Army School of Training Support (where they do the BIT training).
They are a friendly, helpful bunch who like to spread the good word on presentations etc.
BITS course is a top laugh- mine was only the two weekend TA one but I really enjoyed it. Day one is death by viewfoil but the rest was great! I did mine at Fulwood in Preston and i would recommend it to any fellow STAB!
(But don't go to LegEnds night club by the football ground, its fcukin AWFUL!!!)
