I have advised elsewhere, to enlist for the minimum term possible, get what qualifications they can out of it and some really good training and experience in whatever trade/specialisation they wished for.
During their time in (whatever service) they will either like it or not, but can exit as contracted with at least "a trade" and experience behind them.
I have also recommended the easier option of comissiondom first, trade second.
So my answer is Yes! - But use it like it owes you something.
