Troops struggling with mental or emotional problems can no longer be simply told to ‘man up’ ministers have said, as the Armed Forces joined with Prince Harry to try to overhaul the military’s attitude to mental health.

The Prince said he wanted a complete change to how the military sees mental fitness, taking it as seriously as physical fitness.

The Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry will now expand its campaign to remove the taboo of mental health, into providing new training to service personnel, veterans and their families.

Soldiers, sailors and airmen will be encouraged to work on their mental resilience as well as made to feel they are able to seek help.

Tobias Ellwood, a defence minister and former Army officer, said: "We put them in situations that most people will never see and they need to cope with that environment.

“This is to show that there is absolutely a demand to change culturally the attitude, to open up that conversation to say for any soldier, the mind is as important as the body.
