Thanks. Think thats what I will aim to do. Just have to "explain" to the folks about why I spent those years at uni to join as an ordinary soldier.
The Army is very good at taking people thought to be bad by civilians, accepting them at face value and turning them into what they would like to be. It's been doing it for several centuries and so there's no need for you to explain anything to anybody. It's a two way street, by the way.
Besides, there are plenty of soldiers with degrees in specialised parts of the Army.
