I'm 18 and want to join the army, got pretty good GCSEs and i'm currently doing A levels, don't think i'm gonna do too well in these though. I'm currently interested in joining as an ammo technician. Couple of questions: 1. What are the standard entry requirements? 2. Are they likely to push me towards other careers? 3. Once the basic training is completed, what are the different careers available? Thanks!
