:...get out and join some kind of sport club/ team, they will look for team skills and sporting ability..."
This is really very important, involvement in team sports will be something they want to see, if they think you are a 'Johnny-no-friends' who spends his time playing with his x-box and watching bad movies then that will count against you. If you can get references from someone who runs the team sports you are involved in then do so.
"...I don't really understand the career bit as well, sorry if its daft but i thought the army like was a career, i know there are different positions and ranks which require different skills..."
You need to understand the career bit, you need to understand how the various parts of an a modern army work together, don't wait for the careers people to tell you about these things, don't wait to learn them once you are in, find out about them now.
An army isn't just a bunch of guys running about it wilds somewhere, someone has to decide they should be there, that person makes that decision based on information provided by someone else. someone has to get these guys there, someone has to make sure the car, carrier, helicopter or mule they use to get there works and has to keep it working, someone has to ensure they can get there without falling down deep holes or being washed away in fast rivers, someone has to make sure they have the gear they need and the bits they need to take care of that gear, someone has to make sure they are fed, someone has to keep them healthy both mentally and physically. Etc etc.
Use your local library or at a push Wikipedia, look at the links in my earlier post to start with.
"...You also need to consider the politics of the present day. Regardless of wether you agree with a situation, you will be required to serve. I'm guessing your political views may change a lot over the next 4 years so..."
"...If someone asked me 'why do you want to join' i would not have a answer, i just honor what the soldiers do for us and how brave they are and i think its a life experience..."
You really do need to have an understanding of the background behind the various conflicts present and future you may end up being involved in, not perhaps so much because the recruiters might be interested in your opinions, but because you are a human being and should really try to keep yourself well informed about these things. Read a newspaper (not the Daily Mail), Watch the news (not Sky news), listen to the radio (BBC Radio 4).
"...Painting grass with olive drab canvas paint before a Royal visit springs to mind along with painting stones white..."
Something not covered in the recruitment literature, or movies, or PC games is that being in the military can often be quite tedious, lots of shirts to iron, boots to polish, floors to clean, buttons to shine.
