The Roster

CEO / Tactical Instructor
ED GUERRA
Founder - Obsidian Spear Group

Ed Guerra dedicated over 21 years in U.S. Army special operations. He served in the 75th Ranger Regiment as a Recce Team Leader, Platoon Sergeant, and Small Unit Tactics Instructor, shaping the next generation of elite warriors.

 

In 2014, Ed was selected for a Special Missions Unit, where he operated globally as an Assaulter, Breacher, Sniper, and Senior Tactical Advisor. With multiple deployments around the world and deep combat experience, he now leads Obsidian Spear Group—bringing hard-earned lessons to those who face danger head-on

 

"I started Obsidian Spear Group in 2024 to continue a calling that began in the Regiment—mentoring warriors. Some of my most rewarding moments in the military came from training new Rangers, helping them become more lethal, more decisive, and more resilient in chaos. I saw that same need in the law enforcement and civilian world. OSG was born to pass on not just what I learned from success, but also the hard lessons from failure—to equip today’s protectors with the mindset, skill, and heart to thrive in the fight."  -- Ed Guerra
