@MACH5 I'm a CT, been in a good few years now. Happy to take questions. The job is changing from what it use to be, our branch is growing, we are now cap tallied to ships, meaning we do part of ship (cleaning and anchoring etc): soon to be expected to keep gangway (holding a rifle on top deck getting a tan, even when it is raining). We are pretty much required on most (bigger) sea going platforms. Subs are a thing, not a specialist though, so any CT can do it. Lots of sea time, also lots of shore drafts too. So you can get a unique career, no two CTs have really done the same career. Training pipeline is quite long compared to some branches (however I expect engineering is probably longer). However you get promoted at the end, so that is a big win. Things change fast but the next promotion after that shouldn't take too long either. It is sold to everyone as a super nerdy branch, where you need to be super clever, but it mainly involves hardwork and a decent amount of revision but nothing ridiculous. Picking engineer will get you real life quals, whilst CT gets you a BTEC for BT.
