Okay a question for you - and a sensible one, although the answer may be obvious, it's not to me. Why do SIB wear suits to work and not uniform like the rest of the Army? It is not like they are CID working with the civilian population all day is it? From what I can see their customer base wear CS95 all day and they interact very little, if at all with outside organisations and civilians. UIE do similar work but wear uniform and change into suits on the odd occasion when they need to - why don't SIB?
