Basic Wound Ballistic Terminal Performance Facts

By: Dr. Gary K. Roberts 8/23/11 The last 30 years of modern wound ballistic research has demonstrated yet again what historical reports have always indicated--that there are only two valid methods of incapacitation: one based on psychological factors and the other physiological damage. People are often rapidly psychologically incapacitated by minor wounds that are not immediately physiologically incapacitating. Psychological factors are also the reason people can receive severe, even non-survivable wounds and continue functioning for short periods of time. Up to fifty percent of those individuals rapidly incapacitated by bullet wounds are probably incapacitated for psychological rather than physiological reasons. Psychological incapacitation is an extremely erratic, highly variable, and completely unpredictable human response, independent of any inherent characteristics of a particular projectile. The degree and rapidity of any physiological incapacitation is determined by the anatomic structures the projectile disrupts and the severity of the tissue damage caused by the bullet. Physiologically, immediate incapacitation or death can only occur when the brain or upper spinal cord is damaged or destroyed. The tactical reality is that in combat, opportunities for military personnel to take precisely aimed shots at the CNS of enemy combatants is rare due to high stress unexpected contact marked

Armorer Liability: Minimizing Risk and Exposure

Armorer Liability: Minimizing Risk and Exposure By: Chad Mercer There is a lot of confusion about liability, people hear that word and immediately associate it with criminal or civil. I am going to parse some words and offer some guidance so you know what my concerns are. Granted, I worked in a Federal Armory and had lots of established policy and a huge budget compared to what the average department has. However, it was a very litigious agency and we worked closely with the FBI and BATFE. So my scope of experience is a bit broader than most. These aren't two cents, these are two quarters. What I want to be abundantly clear about is this boils down to minimizing two things; risk and exposure. By Risk, this is about Officer/Agent survivability (WINNING THE GUNFIGHT OF THEIR LIFE). As an gunsmith/armorer that is a PRIORITY of our service. We do not cut corners. We provide due diligence to insure that the duty weapon and its accessories are NOT the weak link in the fight. A gunsmith/armorer knows that the second he takes possession or more specifically performs work on a firearm (custody), he assumes liability. This is why gunsmiths and

How I Was “That Guy” but Avoided Being *That Guy*

How I Was "That Guy" but Avoided Being *That Guy* By: Jonathan Halek   "People, men especially, avoid doing things they don't do well". If you consume enough media on defensive firearms use, you'll come across this phrase often. It's usually in the context of "weak" or "support hand" shooting, but I've heard it related to malfunction clearance and even marksmanship fundamentals. It's sexier to show off what you already do well. You "look" good so you feel good. Anything less is an embarrassment in front of your fellow men, and that is a fate worse than death. This is where I was in contemplating my first rifle class. I bought my 1st and only rifle a month before 'Newtown', and the insanity that ensued. For two years I scrounged ammo as I could but was afraid to shoot it. I didn't grow up with guns and am the only real "gun guy" amongst my friends. I had no time behind my rifle and had shot 120 rounds spread over 2 years. I didn't know what the sight picture should be. I didn't know what the trigger press should be. Zero? Not easy when you're shooting 10" groups at 50 yards. I

AAR: Sentinel Concepts Essential Carbine Employment

AAR – Sentinel Concepts Essential Carbine Employment By: Phil Axelrod Instructor – Steve Fisher When: 10-11 October 2015 Where: Nunn, Colorado Cost - $450 Ammo : 1000 rounds (rifle) 300 rounds (pistol, optional) Class Size: 12 students My background and realm of experience - Active duty US Army Infantry Officer, Bachelors and Masters degrees in education and curriculum development/instruction (focusing in Biology), ten years of experience giving basic-level firearms instruction. When in student mode, I tend to watch instructors for more than just the information they are presenting, but also how they present it and how confident they are with the material, their gear, the class size, etc. Gear – I brought two rifles and two pistols with me: 12.5” BCM SBR with Ops Inc 12th Model Suppressor, 14.5” BCM Upper/P-Tech lower M4 clone (more on this later), Beretta M9A1, and Glock 19. I chose to wear my Crye Precision JPC 1.0 with ESAPI plates during the majority of the class, as this is what I wear for work. I was shooting Wolf 55gr Polyformance FMJ .223 Remington and Blaser Brass 115gr 9mm ammunition. I use Aimpoint sights and Viking Tactics padded slings. Intro Steve started off Day One with

You know what really grinds my gears?

  I remember when I first learned how to ride a bike without training wheels(at the tender age of 19). I said to my dad, 'Dad, I can walk just fine. I'm not comfortable on a bike. It doesn't work for me. Walking works for me.' My dad looked at me and said, 'Son, riding a bike may not be easy or comfortable right away, but it's a faster way for you to get to your dance recitals and it requires less work over time.' He was right. I got faster. I'm also very comfortable without training wheels now. Same thing applies, step out of your shitty little comfort zone and make shit happen. If not, you don't have to. It's America, stay on the couch, just don't preach that bullshit to others that are looking to improve and push thier limits.Nothing says 'I don't gun' quite like a 1 or 3 point sling and a drop leg Serpa. - Rich Brauer

The Fight Picks You

By: "Frank Woods", NYPD I have something to say. I will try to keep this short and simple. If you are in Law Enforcement and thus have the authority/ability/permission to carry a concealed weapon on your person when in plain clothes off duty, and you don't, you are either lazy, or you have your head up your ass. On at least three occasions in the last two weeks, I have spoken to coworkers of mine that choose not to or otherwise refuse to carry their weapon off duty. Reasons I have been given upon asking why have been: "I live in a safe neighborhood." "It's uncomfortable, there will be uniformed cops around, I haven't needed to carry it off duty." "Our lives are pre-destined and if God wanted for me to carry my weapon off duty on a particular day, then I would feel compelled to do so. What if something happens and I get shot because I have my gun on me and now I've become a target?" I'll tackle these one by one. The first example is naive. Sandy Hook/Newtown was considered a safe neighborhood. Just because things are calm and quiet on the regular, doesn't mean you're not

AAR: DARC Tactical Urban Sustainment Course (TUSC)

Multiple vehicle drill, contact left and front vehicle is disabled. Moving to the shoot house. AAR: DARC Tactical Urban Sustainment Course (TUSC) 4-7, 20 SEP 2015 By: John D. Remf What this AAR isn't: A complete breakdown of the TTP's and minutia taught in the class. There are reasons for this. The most important is without being there and participating as a team under the eyes of competent instructors, mere words are going to be a disservice. There is a lot more information and experience gained from the course than can be translated into an AAR. What this AAR is: An overview of the scenario, purpose of the class and some lessons learned. The purpose of the Tactical Urban Sustainment Course is an introduction to the problems one would face in the event of a breakdown of order following a catastrophic civil disturbance, either man made or natural. Developing the mindset to find solutions to those problems is emphasized over specific a+b=c mentality. This includes instruction on what to expect when our daily comforts, conveniences, order and security are no longer a reality, and what you can do now, to make that transition more manageable if it becomes necessary. The course

Light and the Inverse Square Law

By Michael Johnson So I've debated posting this for a while because I'm not a firearms expert (not even close), but I wanted to share some knowledge that I do have that I don't think most people understand. I work as a photographer and thus my expertise is in light and working with light. With that intro, I've seen a fair amount of resistance and misunderstanding about lumens and light and how far it reaches and how bright it is. There is a physics concept call the Inverse Square Law. In a nutshell, the Inverse Square Law says that if you double your distance from light source to target, you'll only get 25% of the light reaching your target that you had before. Not 50% like you may think. Double your distance quarter your amount of light. So going from 300 lumens to 600 lumens will only give you an extra 25% reach, it won't double your reach. Twice as far doesn't mean half the light, it means a quarter the light. Thus all these people running around saying 'all the lumens'. Light falls off fast, really fast. So take as much as you can get. Richard Sandstrom pointed out

SME/Mods/Instructors Titles on Forums

Insight by Shane Fitch Not all Forums are created equal. Just because you see someone has a SME/Mod/Instructor/whatever title doesn't necessarily mean that that person is qualified for that title. Yes, there are exceptions to this. Use care and caution when taking in information. As with anything else, check other sources and verify. I treat SME titles folks like I treat Instructors I want to train with. What are their backgrounds and experience? Someone can attend a instructors 'Instructor certification' class but does not necessarily mean that that person is qualified to teach. It does not matter if you are a good american, LEO or MIL wanting to enhance your skill set, do your research.
