WATCH: Wounded Pa. National Guard vet carries woman across Boston Marathon finish line

A nine-year veteran of the Pennsylvania Army National Guard who was wounded in battle carried a woman across the finish line at the Boston Marathon on Monday, and it's all on video.

WCVB Channel 5, an ABC news affiliate out of Boston, captured the footage of the heartwarming moment – a nearly 30-second clip that's been shared almost 7 million times as of Tuesday afternoon.

The man seen in the video is Earl Granville, of Lackawanna County. He lost part of his leg when a bomb hit a vehicle he was in while in Afghanistan in 2008, according to the news station.

Granville has been an avid racer in the past but took part in the 121st Boston Marathon without a handbike, WCVB reported.

The video shows Granville carrying a woman who is holding a large American flag as the two make it across the finish line.

The Pennsylvania Wounded Warriors Inc. showed their gratitude toward Granville in a Facebook post on Monday.

"Thanks to Earl Granville for showing the Boston Marathon what veterans of the Pennsylvania National Guard can do," they wrote.
