Whilst many here have made some valid arguments, I fail to see how axeing an entire service, or handing one fleet of assets over to another service, will solve the problem - lack of funds.
If you wish to retain the same level of capability, you will need to retain the same levels of equipment and personnel, surely? So please explain exactly how taking an entire unit, or fleet, and simply changing the colour of their uniforms, is going to save anything? It will, in fact, cost money in the short term - which kind of defeats the entire object!
