Though I do support your choice to join our Forces, I have to ask: Why do you wanna join the German Forces anyways? England has a great Military. I'm not very good informed about the Royal Army today but I have a good knowledge about the German Forces. I would like to share some of the info I have about that in privat.
Plus I may make some calls and get some info on your current request, it may be less difficult for me to get good info on your case if you want to.
Just contact me via Pm. :thumb:
Edit: about your previous questions- you may of course make requests about which unit you choose (do you have any preferences yet- I may help you with the concrete choice). Normal conscript time for NCO is 8 years, you have the (small) chance of getting more time while serving. Officers have 12 years normally and if you want to become a professional soldier it is adviced to get a Bachelor or Masters degree after the officers school (if you are adjudged fitt for it)- without that it may be difficult though I doubt that- German Forces have a growing problem with getting new soldiers every day.
As 13th said before you may also sign in for standart military service and start with 9 month that may without problems be extended to 23 months (i did that before getting into the Officers career , I was born and lived in Belgium but had a German Passport- I signed in for military duty at the local 'Kreiswehrersatzamt'- they didn't have me listed until I reported in- same with you I guess), that way you would get to know the German forces and it may be easier to enter NCO/ Officers career if you have proven yourself (as I mentioned chances are pretty good especially if you want to go into the Infantry- worst case scenario: you would get a position as NCO in another unit next to your preference... you may change the unit later (small chance)).
Since the only -combat- deployment is with the QRF in Afghanistan at the moment you should chose an Infantry Branche. After that it is the Air Force Infantry and the Navy Forces who have the highest rate of deployments.
Hope that helps a little.
