Hey dude yea im in the army. I thought about going into the engineers but you can do any course in any regiment. At the moment im in the royal signals but looking into other regiments it sounds shit. I'm looking at the blues and royals which are the queens guards. If your joinning up after school you will proberly come to where i am at the moment, which is Army foundation college.
Its still a phase 1 trainning camp but it lasts a year and you do education.
You get used to leaving everyone back home the people you end up meeting become your new family, if you got any more questions just bm me mate.
P.s the army isn't royal because it went against the king back during the civil war :D
