Basically just got to do whatever you want to do. If u really want to go engineers then go for it, they are a cracking corps and as Screw the nut said, there is the opportunity to go commando or airborne and do more infantry type things. But if you really want to do infantry then thats what you should do, just talk to your mum about it and explain its your career and its what you want to do. Don't let other people influence your job choice, its the job that you are going to have to do, potentially for 20 + years, so its got to be the one you WANT to do!! good luck!
