The soldiers from the Army Air Core based at Wattisham, Suffolk, were swept away by an avalanche during training at Coire an Lochan in the Cairngorms, Scotland ten days ago.
A mountain rescue team, which included Breagh, was sent out to find them in treacherous conditions.
The plucky pooch managed to sniff out five of them and licked their cold faces until they came round.
The men were very bruised and battered because they'd been bashed against rocks in the fall.
But Breagh kept them warm and comforted for 80 minutes until the team could helicopter them out.
She even snuggled down with the most seriously injured soldier to make sure he was alright.
Her name means "beautiful" in Gaelic and she is certainly a beauty in the eyes of the lucky soldiers.
Let's hope she was given some extra doggy treats too!
