Command Line Concepts builds software, produces training media, and runs instruction for people with a job, a family, and a match on the calendar — tactical athletes and practical shooters who want to perform under pressure without living at the gym or the range.
Get in touchWe combine product and engineering experience with real time on the line and under a ruck. Everything we make has to hold up in the field, on the clock, and in the hands of busy people.
We design and build mobile and web applications, along with the connected tools that support training and performance.
We produce practical, no-filler training content for shooters and tactical athletes across video, print, and email.
We program and coach for two-gun and tactical competition, built around limited weekly training time.
Command Line Concepts was founded by Brian Sells, a former U.S. Army Ranger who served with the 75th Ranger Regiment and the 82nd and 101st Airborne Divisions.
After the Army, Brian spent years leading product, engineering, and delivery teams building asset-tracking hardware and software for Department of Defense customers. Command Line Concepts brings those two worlds together: disciplined engineering and real-world training, packaged for people who have jobs, families, and limited time.
Our approach is simple. Remove the guesswork with a clear plan, make it easy to show up consistently, and measure what matters.
