The staggering cost of providing air conditioning for American troops in Afghanistan was discussed on the Today programme this morning - I've tried unsuccessfully to find a link on the Beeb's site. A retired US Brig. Gen was explaining all. Apparently it costs $200 million (?) a year to try and air con their tents! The figure represents roughly a third of the entire British defence budget!! The cost of a gallon of fuel is $45 a gallon by the time it reaches Theatre and this, amongst other things, drives the cost up. The logistic effort, cost in LSD and in 'blood' (as the General said) is tremendous. He did go on to say that he's surprised that they don't make the use of insulated tents the norm. Fascinating. One then thinks of what our forebears went through whilst fighting it out in the North West Frontier in any number of actions that are recorded on the table mats on the table of the Mess. One also thinks of all those there NOT living in an air conditioned tent.
