In reply to Fauve Ferrier:
Hi Fauve,
you may be outside the age limit but, if you are a specialist you can still join the regulars if they are short in that specialty area. (I'm talking specifically about the Navy as that is what you mentioned)
There are few good points here but a lot of it is service dependant. There is a massive difference between a recruiting office and a recruitment team. Expression of interest via the careers office followed up by the recruitment team followed by an acquaint visit, interviews etc. Compatibility tests, employment checks, medical etc etc and as above, if they need you in a certain specialist area just because you're over the age limit according to the website, doesn't mean you won't get in.
As far as other aspects go, you will have a war role which will you will need to maintain currency in and dependant on which unit you are based at, this may come before your primary trade.
As far as being an Officer goes, again Navy specific, you already have the qualifications to apply for AIB (Admiralty Interview Board) so if you are needed in a specific specialty area and you express an interest to commission at initial interview and again impress on the acquaint and to the recruitment team, you'll have a good chance to go to AIB but if you fail, (again assuming they need your specialty) you can still join as an other rank.
If all the above fails and you are not required for the regulars, they the same process applies for the RNR (Royal Navy Reserves).
Hope this helps, Den
