Regular poster but NC for this.
Not many people know that ordinary soldiers are not allowed to speak to the media without permission - they can be sent to military prison if they do. Because of this, there is virtually no information out there telling people what life is like for the average squaddie. Everything is controlled by the Army recruitment people.

This article tells you what it's really like for many recruits. I have so many friends who experienced the same as this guy but they are terrified of speaking out. Please, please, read this carefully if your kid is talking about joining. This is not an isolated issue. It is absolutely systemic. Feel free to PM me if you want to know where to find more sources of independent information about army life to read, alongside the official recruitment materials, before you or your kid make any decisions.
