OK, here is a starter for ten.
There is often something in the wider system, and not just IED hunting, that causes friction, and often increased fatigue. I think it is a reflection on Britain that this item continues to be used, as it is often cited as poor value for money, and not fit for its purpose. Although many foot soldiers have little confidence in this item, it continues to be a deciding factor in many conflicts we are involved in.
I am not sure if it has a proper NSN, but this item is generally referred to as 'M.P.'
