When you think of “American power,” what comes to mind? The “BRRRTT” of an A-10 Thunderbolt II, razing enemy hideouts beneath it? What about a C-17 Globemaster III aircraft offloading pallets of supplies and munitions to ground forces? For many infantry, it could look like a battalion of Soldiers with M4s clearing a battlefield of insurgents. But the Air Force band? What’s so “powerful” about them? Well, a lot.
