The A-10 Thunderbolt is a bit of a miracle. It flies slow and low under the most cantankerous weather conditions while delivering highly advanced weapons to troops that need them most.

Imagine the moment behind a sliver of cover, knowing precisely how many rounds are between capture and freedom when the heavy droning sound of the A-10 cascades in from the distance.

The deep breath of relief inspired by the A-10 is like noting else in the world because no more reassuring sound exists than the twin engines of the A-10 Thunderbolt screaming in from the distance.

That's what you think anyway, until you hear the 30mm Gatling gun pounding 3,500 rounds per minute at the guys just trying to end you.

That's when it hits and you finally understand the truly most reassuring sound you'll ever hear.

The A-10 is an old plane, that continues to provide massive air support to ground troops with that cannon and missiles that can take out a main battle tank in a single shot.

Sometimes old is good. And sometimes a single sound can turn an entire battle around.
