/// The same reason we have pointless police helicopters.///
I don't think you could say that they are pointless, they do valuable work.
They can get to an incident in a fraction of time that it would take any other response vehicle, often in areas where other vehicle can not reach.
What I must agree with you though is the small number of helicopters deployed in Afghanistan, compared to the number in England & Wales, taking into consideration that the land area of Afghanistan is four times greater than England & Wales.
But then that is yet another matter.
