Prince Harry continues to advocate for service members and mental health causes. Today, HeadFIT - a service he began to develop three years ago - launched its 24/7 online platform with mental health assistance and self-help tools for the military.

The Duke of Sussex served ten years in the army himself, and is a frequent supporter of veterans and military personnel.

Prince Harry speaks on HeadFIT, his secret project

Prince Harry delivered a statement upon the service's launch:

"HeadFIT has been almost three years in the making, and I am extremely grateful for everyone who has been on this journey with us. Everyone who has worked on it, to create what we have today, should be incredibly proud and excited for the impact it will have.

"I've long believed the military community should lead the way for the rest of society. For too long we have been waiting for problems to arise and then reacting to them. HeadFIT is a proactive approach to mental fitness, focusing on our own potential to increase our performance, using proven methods in sport science.

"This is about optimisation of self. This is about being the best you can be. This is about gaining an advantage, whether facing an opponent or overcoming a challenging situation. This is about building resilience that will match that of most world class athletes and prepare you for everyday stress. To be HeadFIT, is to be at your peak performance," his statement concluded.
