The value of interactive training cannot be overstated enough. If your training does not include this, you are not doing yourself or your agency any favors.

The world changes drastically when we go from the flat static range into a more realistic interactive training environment.

We have learned over the last 25 years of conducting interactive training is that if students have not mastered the static level of training (fundamentals), their odds of winning a real gun fight are low. In other words, if you can’t hit a static target at close range (4 yards with bullet hole through bullet hole) with no stress on you, how can we expect to do so while under stress?

The technology we use for our interactive live fire training is called CAPS. Here is a link with more info https://centermassinc.com/firearms-training-simulator .

It is the next best thing to being in a real gun fight as you are using your firearm, with your ammo, with your judgment, and your accuracy on the moving human opponent. Unlike the static targets we all practice shooting, in the real deadly force encounter the bad guy is always moving, at least to some extent. Further, the moving human opponent does not move like mechanical moving targets. The moving human opponent changes direction, speed, levels (up & down), and angels consistently, not to mention sometimes shooting at you or someone else.

At nearly every single LE class we have taught in the last 25+ years, our students spend time on our two CAPS live fire simulators. Our students have shot many people now and some of them have credited their performance under stress to the lessons they learned on this system.

Our mantra at Center Mass is “you can’t miss fast enough”.
The stats you see in this pic are from our recent Fi****ms Instructor School (pistol & patrol rifle). The students shoot on the system typically on day 4 of the 7-day class. The results you see are about average, which is not good enough, but how would they have known otherwise? This experience and data provide invaluable feedback to the students about how important the static level of training is to their performance under stress and how important accuracy is, not only to their survival, but that of their partners and innocent citizens.

The following are descriptions of each of the three scenarios along with what we are assessing and our instructors’ observations.

Scenario #1 Domestic: Female screaming he’s gonna shoot me. Female flees out a door wall with male pursuing coming down steps and shooting at her.
• Student assessment is to clear handgun malfunction and hit the life-sized moving human opponent at 7-yards.
o Handgun is set up purposefully with no round in the chamber. The student must press the trigger when appropriate, get the click and expeditiously clear the malfunction, and then, if possible, put accurate fire on the moving male offender.
o INSTRUCTOR Observations: See hit ratios. More than half the class did not tap the magazine first.

Scenario #2: Active shooter: Male shooter in a school actively following and firing at numerous fleeing kids and eventually catching a little girl and then carrying her away as he continues to shoot at responding law enforcement.
• Student assessment is to transition from the patrol rifle to the handgun and then hit the life-sized moving human opponent at 7-yards.
o The patrol rifle is purposefully set up cold (bolt closed, rifle on safe, no magazine inserted). The student must press the trigger when appropriate, get the click and expeditiously transition to the pistol, and then, if possible, put accurate fire on the moving male offender.
o INSTRUCTOR Observations: See hit ratios. Transitions way to slow. Students slowed down with pistol shots, fired fewer rounds and had the highest hit ratio of all 3 three assessments.

Scenario #3 Active shooter: The student is a part of a contact team and assigned to cover a hall while kids are actively running at the student and shots are being fired in the background (unknown where the shooter is located at this time). Eventually, a shooter comes out of a door moving very quickly laterally shooting automatic fire at the student.
• Student assessment is to properly load the patrol rifle and then respond to the active shooter and hit the life-sized laterally moving human opponent at 12-yards.
o The students are given more than adequate time to properly load their patrol rifle and then hold the hallway in this scenario. Eventually, the shooter appears moving laterally very quickly to the left, and suddenly back to the right, while shooting at the student. The student must use the tracking method of engagement to put accurate rifle fire on the male offender.
o INSTRUCTOR Observations: See hit ratios. Three students (of 19) failed to load their patrol rifle properly and got the dreaded “click” when they needed their rifle to work the most. That’s 8.4% which is higher than the 6% we observed at the 2025 NPRC.

I hope you enjoyed this information.

As we continue to celebrate our 30th year in business, we’d like to share a bit more about CMI’s history. Many people in the law enforcement profession think that CMI created the SWAT Operator Insignia, but that would be wrong. This iconic insignia was created in the very early 1990’s by a group of very respected and dedicated Livonia Michigan SWAT Team members. The insignia was an instant hit with the team and a senior member of the team who is now deceased, acting on behalf of the team, gave all the rights to the insignia to a local business in return for “at cost” pricing whenever the team ordered product. That business then began selling the insignia to its client base. CMI’s founder observed throughout the early and mid-90’s how robust that businesses sales of the insignia were at various SWAT events throughout the state of Michigan. When CMI first started in 1996, we really struggled as our founder was a cop and not a businessman. He knew at least that he needed a way to make consistent cash flow to keep the business alive. In 1997, he asked the business who owned the SWAT Eagle, now known as the SWAT Operator Insignia, if he could become a dealer and begin selling the product on their behalf. The request was granted and CMI put the insignia on a new technology called the internet, and a website. CMI’s cash flow problems were solved virtually overnight as sales of the SWAT Operator Insignia began to flow in from all over the country. Eventually, CMI bought out the rights to the SWAT Operator insignia from the original business. However, after that deal was done, our lawyers told us that we had to get the copyright assignment from the original artist to legitimately own all rights. A member from that SWAT team gave us the original artists name and we found that person on myspace (yes, we are old), contacted them, and closed a deal securing the copyright assignment making CMI the 100%, unequivocal owner, of America’s SWAT Operator Insignia. The only credit that CMI can take in the insignia’s evolution are improvements to the design and that we were the catalyst in its nationwide marketing. The credit for its inspiration goes to, and shall remain with, the members of the early 1990’s Livonia PD SWAT team who had the creativity and vision to come up with the framework that resulted in this insignia. An insignia they believed encompassed the SWAT profession and would help improve es sprit de corps. Their creativity and vision have proven to be admired by SWAT cops across the country and beyond. For this we are thankful, and credit must be given where credit is due. LPD SWAT.

As we continue to celebrate our 30th year in business, we’d like to share a bit more about CMI’s history. Our company’s training division opened in 1998 offering three classes to law enforcement. Patrol rifle instructor, basic police sniper, and active shooter response. The pictures in this post are of a news article about an active shooter class we provided in 2000, up in Alpena Michigan, along with its instructors (Sherman, Lego, Traylor, & Felts) and a January 2002 letter from the agency that insures many government entities in the state, Michigan Municipal Risk Management (MMRMA), recognizing our expertise. At the time, the active shooter response school was a difficult task to sell. When Columbine happened in 1999, I was in the second week of Police Staff and Command school with 50 other Metro Detroit police command officers. I’ll never forget how the instructor went around the room and asked each student what they thought about the law enforcement response. I was probably the youngest student (32) with the lowest rank (sergeant), and I had great respect for the more senior men (age and rank), but I could not believe my ears when most of them focused their answers on how well they thought the involved agencies managed the media. Not even one spoke about how lives could have been saved if we did anything different tactically. I was the last student to answer the instructor’s question, and I told him and the class that our profession failed by not having properly trained, armed and equipped patrol officers to make entry, hunt down and stop the offenders. Rather, we allowed the offenders the time and space to kill and injure as many people as they please. I was ostracized by the class because of my position, but I didn’t care. During every break it seemed like multiple people would try and get me to change my mind, but I respectfully refused. My detractor’s position was always three-fold, in that I should not second guess our brothers and sisters, that sending patrol officers in was too dangerous, and that police officers’ lives are more important than anyone else’s life. That school was the longest 10 weeks of so-called education I ever endured partly because the school absolutely sucked and because I had to consistently defend my position while trying my best to educate some pi**ed off senior cops. In the end (after school was over), and to the credit of many of my fellow students from that class (even detractors), their agencies sent their officers to our active shooter response schools as we were the only entity providing such training in the state. We are very proud of the role our company played in helping to change the paradigm of how law enforcement trains and responds to active assailants throughout the state of Michigan.

As we continue to celebrate our 30th year in business, we’d like to share a bit more about CMI’s history. We once thought that having the military purchase our tripod-rifle rest sniping packages to support the war effort was the highest honor we had ever received. However, having one of its legends tell us later how he used our product on the battlefield, was the greatest honor that has ever been bestowed upon our company. Chris became our friend in 2009 when he graciously donated his time to a bunch eager to learn police snipers. This picture of him is at CMI’s 2010 National Patrol Rifle Championships in Metro Detroit, where he once again, donated his time to help cops get better at their craft. Thank you Chris, and may you rest in peace.

If you are a police sniper team leader or trainer, I’m begging you to please run this drill with your snipers as soon as possible. In 30 years of training police snipers, I can tell you that many believe they are much more capable than they are and the only way to challenge that assertion is to make them put their money where their mouth is. This drill will help you do that and hopefully, an invaluable lesson will be learned on the range and not on a call out.

This week Center Mass celebrated its 30th year in business. As its founder, I cannot think of a more appropriate way to celebrate than teaching police snipers. Today, these LEO’s graduated from our basic police sniper school. We wish them all the best as they begin to serve and protect their communities in their new roles.

I would also like to thank my wife for allowing me to gamble everything we had so I could follow my dream. In addition, I want to thank our incredibly dedicated and loyal employees (present and past) and instructors, who have built our business into what it has become today. Finally, I want to thank our lifelong customers who have graciously allowed us to serve them. I am forever grateful to all of you.

NPRC is October 17th.

Some CMI / NPRC history for you this beautiful Sunday morning.

02/13/2026

For 20+ years we have done our very best to reduce the possibility of student injuries. Yet, in nearly every basic police sniper school, the following observations are relatively common despite the training, warnings, war stories and close supervision that the students receive:
1. The obligatory Day 1 scope bite.
2. The Day 2 realization that (insert your state) weather sucks.
3. The occasional Day 3 shoulder & chest bruising caused by having the rifle too low during off hand shooting drills. This makes the rest of the school miserable.
4. The very common Day 4 “my feelings are hurt sad face” because I’m not the best in the class. In fact, the cop from the poorest town ever is out shooting me and my $5K semi-auto rifle / $2K mildot optic with his crusty old 700p with a standard duplex reticle! And what, not everybody passes? Everybody gets a trophy where I come from….
5. The occasional Day 5, “I’m down to my last chance to qualify” twisted ankle/knee excuse and skittish question, “can I come back and try my last time after I’m healed up?”

Its only 5-days long (60-hrs & 500-rnds). Simplicity and repetition are the keys to spinning the guys up to a basic level of competence fast. So, after the 1st day, the pace is pretty quick for a cop class. If they are not in decent shape, don’t have any sort of a military experience or went through a coffee and donuts SWAT school, this little course can chew some cops up. There’s no formal PT as such, it’s just that all the running up and down range, carrying equipment, getting up and down hundreds of times and crawling takes its toll on some.

Every year, every location and every group of students always makes this class an adventure.

In the end, nothing matters except for the student’s success on the street, in the battlefield of our justice systems (criminal & civil) and the battlefield within themselves. They must win all three or their life can be ruined. We hope to see you or your officers at a school this year. https://shop.centermassinc.com/info/le-training-schedule
