Richard "Mack" Machowicz, former Navy SEAL and host of the popular show "Future Weapons" on Discovery Channel, passed away on Jan. 2 following a protracted battle with brain cancer. He was 51.
His good friend and fellow SEAL Craig "Sawman" Sawyer was the first person to confirm the news on Facebook, writing the following:
I’m saddened to share that we lost friend and teammate, Richard Machowicz, to his brave fight with cancer. His private messages and phone conversations have remained strong and inspiring throughout. An amazing man in so many ways ... His strength of character and integrity were outstanding. May God rest ‘Mack’ in his loving embrace and comfort his family through this difficult time. See you on the other side, brother. Honored to have known you.
Fellow SEAL Brandon Webb, who runs the website SOFREP, wrote a tribute to the departed Machowicz which talked of his "nearly fifty-two years of living by example," Business Insider reports.
