In the New Zealand Army we have been used for tasks that are not what I would call a good use of the Militarys time on a few occasions, the worst was being film extras for the lord of the rings for about 2 mth's. I was talking to two soldiers from Ireland and they did the same for Brave Heart.
I have started this thread to see if other defence forces have had the same thing happen and would like to hear back from any one mucked around with non-military tasks.
