If anyone is a fan of the tv show "The Voice" then they might remember a contestant that was wrongly dumped in the battle rounds named Angie Johnson. Angie Johnson is now a Technical sergeant in the USAF and deploys with a musical band known as Sidewinder. They have many videos on youtube including the one that got Angie on the voice, an improve of Adele's Rolling in the Deep.
Angie Johnson's The Voice Blind audition (Heartbreaker)
Here the band is deployed and putting on a show for the troops. A time to let them feel free of the constant fear of being bombed or mortared at any time. To let them feel a piece of home after being gone for so long. If you have never been deployed then you can never understand, it is a situation that the only way you could understand what its like is to go through it yourself. I just thought I would share a few links to their videos.
