As a very dedicated civilian who trains regularly, Spartan Development Group is an outstanding resource for growing and grooming your skills in nearly all aspects of shooting. Mark is a great coach and makes every effort to understand what his students need in order to make the material as relevant and valuable as possible. Mark is extremely focused and extensively trained by some of the most respected instructors in the industry. His knowledge and experiences provide students with a unique and versatile training opportunity. I have trained and improved in the following areas under SDG’s instruction: handgun, carbine, force-on-force scenarios, room clearing, use of barricades/structures, fighting in and around vehicles, urban defense, precision applications out to 1000 meters, 2 gun competitions, and shooting under night vision. I have also received an incredible amount of advice on selecting the best equipment. Everything from: weapon components, to night vision, to battle belts. Whether you’re a new shooter looking to understand weapon zeros, a mid-tier shooter looking to take things to the next level and understand the “why”, or even an advanced shooter looking to tighten up your game – I highly recommend training with Spartan Development Group.
