Need You Now hitmakers Lady Antebellum have collaborated with National Geographic, Musicians On Call and iHeartMedia to launch a new social media campaign, which aims to honour and support veterans, troops and their families.

Through the campaign, the National Geographic TV network will produce a music video for the band's hit, Army, where fans can submit images and videos via #MyArmyContest, and Hillary Scott of Lady Antebellum commented 'Throughout our career we have been lucky enough to meet some incredible military veterans and their families.... We are looking forward to watching the stories that come through and create an incredible music moment that will also recognise the heroic sacrifices of our troops and their families'.
