A heartwarming video has emerged of a man finding out his wife is pregnant during his Air Force Basic Military Training graduation.

The footage, shot earlier this month near San Antonio, TX, USA, captures the moment he finds a sonogram image of their ten-week-old baby in a birthday card from his wife.

She explained online that she realised she was pregnant just three days after he had left and decided to wait to be reunited with him to announce the news.
