The touching moment an Invictus Games competitor comforted a fellow veteran suffering from PTSD has left spectators in tears.

British mine warfare specialist Paul Guest was visibly shaken when a helicopter flew by during his wheelchair tennis doubles match at Sydney Olympic Park on Monday.

The 54-year-old, who was injured serving during The Troubles in Northern Ireland, was so overcome with emotion he was unable to play and needed to be comforted by Dutch teammate Edwin Vermetten, who realised he was suffering.

Guest served in Northern Ireland for the British Armed Forces before he suffered injuries to his neck and spine while on duty in 1987.

Following his medical discharge, the former Navy servicemen has attempted suicide four times and has since been diagnosed with post-traumatic stress disorder.

As play was interrupted by the sound, Vermetten rushed to the other side of the court to comfort him.

The Dutchman then grabbed Guest by the shoulders and pulled their foreheads together before he sang to the man in a touching moment of camaraderie.

Vermetten described how he used the popular anthem 'Let It Go' from the Disney film Frozen as a way to help Guest repress the memories that were flooding back.

'I took him by the face and said 'Look at me. We are a team so let it go,'' Vermetten said, according to the Invictus Games website.

'Look into my eyes and sing the Frozen song, and we did.

'For him, this was the moment he let go, and he did, he literally let it all go,' he said.

As the pair embraced each other and sang, the raw and confronting moment left many spectators in the stands in tears.

After Guest was consoled by Vermetten, the pair - who only met days ago and have already built a strong friendship - went on to win their match in a third set tiebreak for a 7-5 5-7 (11-9 tiebreak) win.

Guest, who also competed in the 2017 Invictus Games in Canada, has said he became involved with the event after his wife introduced him to Help for heroes.

He previously told The Clacton Gazette the games have given him 'something to aim for' and he is 'proud to be representing my country one again'.

'Pulling on the Invictus Games uniform is like pulling on my Navy uniform.

'Without Help for Heroes and without the goal of the Invictus Games I honestly wouldn't be here today,' he said.
