Mat Best was an Army Ranger. He’s an entrepreneur. He’s a passionate advocate for veterans. He’s a YouTube phenomenon. And he’s now a best selling author. Best’s memoir, “Thank you for My Service,” is a no-holds barred, highly irreverent and oftentimes inappropriate recounting of his experiences during 5 combat tours in Afghanistan and Iraq.

Thank You for My Service is a compelling read and continues Best’s advocacy for vets and his businesses. Best is a staunch supporter of veterans. He is the also co-founder of Black Rifle Coffee Company, not only roasts and sells specialty coffee, but hires veterans and shares a portion of its profits with vets, first responders, and law enforcement.

Best chatted with Stratfor’s Chief Security Officer, Fred Burton about his book, his advocacy and his businesses for the Pen and Sword podcast from Stratfor.
