"I have goosebumps now, so amazing, so excited" says Cook.
Her new single "Airborne Ranger Infantry" is based on poems her father wrote while in the military.
"The poems are from my dads experience. Just family,friends, sitting around camp fire talking. It's real from a soldiers perspective" says Cook.
The day started at a battle scene.
"We shot footage of one of them getting shot and others rushing to aid" says Roman White, the Director of the music video.
Some of the soldiers were actors, but others were men who have actually experienced this type of action in real life and the man that inspired it all also makes a cameo
"We have 5 or 6 real vets including her dad" says White.
White says he wanted every aspect of the video to capture the heart of the song.
"At the end of the day when the edit is done it's gonna be an emotional piece, you have these guys out in middle of horrible circumstance surviving together" says White.
Even the white fabric you see in Kristy's performance scene has special meaning.
"The opening line of the song, my hand is running through fabric and then we open it up and reveal what it is and it's parachutes from soldiers who were dropped in blind battlefields" says Cook.
Cook says even though the lyrics say airborne ranger the song is to every man and woman who have served.
Her small way of saying - thanks.
"It means something to me to sing something so emotional"
