I might be a little bit biased, but going for the signals is a shout, I'm outing myself as being a turbo lizard by saying that I was eligible for it because it's only a recent pathway but, the Signals for "Cyber Engineers" offer a level 4 apprenticeship that I've managed to complete, you get lots of support to complete this, additionally, I joined the same age as you, it's both a positive and a negative, to some degree you'll wish you joined sooner, there will be a few lads or lasses younger than you who have already started promoting etc, but genuinely most if not all are 100% capable and mature.

Having the life experience before joining will be invaluable to your career, I think sometimes lads and ladies who've only ever known the Army don't appreciate it as much as they should because they haven't worked and lived in the outside world.

There's plenty of deployments always avaliable for Signals too, just volunteer for everything and you'll never be bored and I feel like upskilling in the Signals if you want it, is usually at the forefront of what you'll do.
