Behave - go Port Op. As a RLC Soldier you'll get all you licences anyway to drive C+E etc and then you'll also get you boat licences I believe. You can further specialise if you desire. Also get to travel, support exercises etc. and deploy on ops but in support of the navy.
And then there's duty free too.
As an RE Driver, you'll do combat engineering then get posted to an RE Sqn MT which will no doubt be on constant ops.
