As part of an elite team of Marines, Craig Grossi was sent on his most dangerous assignment to the Sangin District of Afghanistan. He expected to face harsh conditions and violence from Taliban fighters. What he didn't expect was meeting a stray dog with a big goofy head and little legs. From that moment on, they were inseparable; whether out on missions or back at the base, the dog named Fred went along. When the time came for Craig to leave Afghanistan, he knew that Fred had to leave with him no matter what.
