Can you not find the information in any official resources and literature? A degree of initiative and resourcefulness is necessary for most higher level study courses. A random query, with no context, on an armed forces career bulletin board, is unlikely to be the most effective channel for getting the information you desire.
Can I suggest you provide more context, and tell people what you currently know and ask if anyone has applied for, or completed, the apprenticeship scheme. It's not a good idea to make the reader do your work for you.
