When are you due to start training?
As said 42 cover majority of maritime tasks although of course 47 will have LCs based on the likes of Albion.
Advice. If you've been through interview and are starting training soon you should know what each unit does and where they are in the world. The information is not difficult to find. Have a look on Instagram and Facebook pages. Rightly or wrongly the Corps advertises exactly who is where and what they are doing.
Or if you'd like more detail, subscribe to the Globe and Laurel. Perhaps set yourself a project. If you dont already know, learn the Units location, name of the camp, and what that Unit is up to recently.
