This is a major "tin hats" on time but I feel that given the shrinkage of the services that is coming , including the size of the army which might well be smaller than any time since the Boer War (which then had a far smaller logistics tail than today), vast savings might well be made by forming a single service. I am not thinking of the Canadian model which proved to be deeply flawed but maybe something of the lines of the US Marines - which is about the same size anyway as all the UK forces. Now traditionalists will hate the idea but individual units within the single service would still have their own identity - the Royal Blankshire Fusiliers would still be the Royal Blankshire Fusiliers - but the overall structure of the forces would be simplified. Officer training (for instance) would be performed centrally; subsequently individuals would follow the career path they chose. Some of the current lunacies will disappear (who controls helicopters is a classic) ... Just an idea ..... As I said I fully expect to get flamethowered for this but WTF !
