Well, others have explained it to you a lot clearer than I can be bothered to. This country will always require defending and in this day and age the way to to do that is from the air. That is the primary role of the RAF. Governments of the future will not always be so keen to send our forces around the world. Hence why the army should be the ones afraid of their future. They only have 4 years to decide best how to reconfigure themselves because after the war has ended and you all come home, there ain't gonna be a lot for you to do.
Best you all get your thinking caps on.
Watch with interest which branch of the armed forces are most likely to help out with a humanitarian crisis in east Africa over the next few months. I didnt see the army delivering aid to Ethiopia, Pakistan, Haiti etc over the years.
Yes, the RAF supports the army, but that isn't all it does. Please remove your head from your anus and have a read of something.
