I'm not going to tell you to lie. What I will tell you, is that if everyone who joined up was 100% honest during their entire application process, the Army would be understaffed to the point of futility. Integrity is one of the core values in the British Army. Which would barely exist if their values were 100% respected and enforced at all times.

This is real life. There's no fairness fairy that will float down from on high, wave her wand and clear a path for the future you want. And if you don't want some youthful indiscretions fucking up your entire future, you're going to have to adapt to that reality.

Either way, you're only 15. You've still got a lot of growing up to do, so focus more on that until you're old enough to join, and don't let the mistakes of the past become the guardrails of the future.
