The Defence Secretary has tweeted to encourage British troops to reach out if they need help with their mental health, coinciding with World Suicide Prevention Day.
It comes as the charity Combat Stress told Forces News they had more than 2,200 new veteran referrals over the last 12 months.
The charity is also encouraging more servicemen and women to seek help through online sessions after piloting what it calls 'Tele-Therapy' - a service aiming to make therapy more accessible.
Gavin Williamson says he wants to "make sure that none of our serving personnel or veterans are suffering in silence", and highlighted the launch of mental health helplines and mental health support guide, the latter being released last week.
Samaritans, who launched the mental health support guide with the Ministry of Defence last week, have been given specialist guidance to help military personnel.
The guide is designed to help armed forces personnel spot and support someone struggling with their mental health or considering suicide.
All military personnel and reserves will have access to either a hard copy or digital version of the booklet.
In February, a helpline to give forces personnel suffering from mental health problems round-the-clock support was launched.
You can contact Samaritans any time on 116 123 or the Military Mental Health Helpline can be called on 0800 323 4444.
