Could you help relieve squaddie stress?

Every year a third of the servicemen and women who leave the military will experience mental illness. Many will also experience homelessness, drug or alcohol addiction and unemployment.

Have you served in the armed forces or have you got family or friends who have? Do you live or work in London? If so, you could volunteer to help an ex-soldier adapt back to civilian life and maybe even prevent problems such as homelessness, drug and alcohol addiction and unemployment.

I think mentoring is one of the most impactful forms of volunteering there is - for you and the person you mentor. With Rememberance Sunday just around the corner, what a powerful way to remember and say thank you to those amazing people that have fought for our country and now desperately could do with your help.

Our Chief Executive Helen Walker talks exclusively on the Guardian Society website about the launch of our new mentoring project for ex-servicemen and women and is calling out for 70 mentors to sign up.
