Links to some of the best tactical information on the web.  If you have some free time, check them out this weekend.


Q-Tips: An alternate way to install an AK cover



John Benner from TDI showed me this method of replacing the dust cover on an AK many years ago.  I’ve used it ever since.  They key factor is not seating the rear of the recoil spring all the way in the notch where it belongs.  Only place it about half as deep as you normally would, put the dust cover on, and run the bolt.  If you are interested in AKs, check out the two part series on “How to buy an AK” part ONE and part TWO.



Bad habits bite


Pay attention when you are reholstering!



Practical advice on situational awareness and firearm self-defense


If you enjoy Massad Ayoob’s advice, here is a nice collection of some of the videos he’s done over the years.



The Art of Blending in: 5 Tips from a Counterintelligence Special Agent


Some good advice here.  Dress how you want, but I think blending as much as possible is a good goal.  That means you shouldn’t look like you walked out of a 5.11 catalog.



Pelvic Shooting, the Best Worst Option


A decent summary of the issues involved with pelvis shots.  Please pay no attention to the author’s retention shooting techniques.  They are sub-optimal at best.  Jeff Gonzales shares his view on the topic in Anatomy 101.



SHTF Armorer: 10 Basic Items For Your Armorer’s Kit


I like to be able to fix any gun that I carry.  Here is a good listing of basic armorer’s supplies you need to have in your workshop.


Two-thirds of San Diego County police shootings involved drugs, report says


A useful analysis of 358 police shootings in San Diego County.  It provides a lot of statistical information about the situations officers find themselves in during a gunfight.



The Handgun as an Impact Weapon


The fine art of pistol whipping.  I cover this topic in all of my extreme close quarters shooting classes.  Malfunctions are commonplace when shooting in the clinch.  Sometimes it’s faster to incapacitate your attacker by hitting them with your jammed gun than it is to clear the malfunction.



Urban Survival & Lock Picking


Lock picking is a very useful skill to acquire and is not hard to learn.  If you are interested in the topic, Practical Lock Picking is the definitive text to read.



The Window Drill


An easy drill for correcting a flawed drawstroke.



Genetic Markers and Immune Response Reveal Origins of PTSD


Fascinating stuff.  Did you know there may be a genetic predisposition for acquiring PTSD?



You CAN Be Too Safe


Firearms safety rules are important, but some folks use them as an excuse to avoid important elements of training.  As the article says “But zero tolerance means zero thought or consideration (a kind of non-thinking in which employees of the DMV excel).”



Cardiovascular Demands of Deer Retrieval Methods


For my deer hunting friends who may not be in the best shape:  using a harness to pull your dead deer out of the field is less likely to give you a heart attack than dragging it the traditional way.  This article from the same journal is another interesting read.  We’ve been taught to rapidly cool hyperthermic patients by using bags of ice in the armpits, groin, and neck.  Instead, placing them on palms, soles, and cheeks may create faster cooling.



You Can’t Always Be There, or “Situational Awareness Skills For Kids”


My friend Marcus Wynne shares a valuable drill that parents can do with their children to help them resist predators.



The 7 Best Mobility Exercises You Haven’t Tried Yet


The stretching exercise you are doing before and after your workout probably aren’t helping you at all.  Try these mobility drills from Kelly Starrett instead.  They are purely evil torture devices, but they will keep you healthy.



Tourniquet Lessons Learned


There is a reason that the Committee on Tactical Combat Casualty Care only recommends two tourniquets, the CAT and the SOFT-T.  They work better than the others on the market.



UC Santa Barbara Shooter – Video Analysis


From the authors who wrote Left of Bang, an analysis of the body language and vocal tonality of the Santa Barbara active killer in a video he recorded before his shooting and stabbing spree.  Pay attention to the clues the authors identify and look for them in the people you deal with in everyday life.



Marathon Bombing Response Report: It’s Ugly



WeaponsMan provides some commentary on the recently released Boston Marathon bombing after action report.  It isn’t pretty.



 Kenya University Terrorist Attack


Last week 4-5 Al-Shabaab terrorists attacked a university in Kenya, killing approximately 150 people.  There are many lessons to learn from this attack.  Pay special note to the fact that the attackers conducted extensive planning and utilized a sniper to dispatch all security personnel during the attack.  The two documents below (from NYPD and the Railway Alert Network) are both quality unclassified, open source analysis of the attack.  Read through both documents and think about what you might do if caught in a similar attack here in the USA.

The Child Soldiers Of Mexico’s Drug Gangs

Mexican drug cartels supply the majority of cocaine and heroin consumed in the United States.  Most people have no idea how brutal the cartels are.  It’s estimated that the cartels have killed more than 83,000 people in Mexico over the last eight years.  What’s even more astonishing to most Americans is that cartel assassination squads operate freely here in the USA.  This important video describes how the cartels recruit and use teenagers (and younger children) as lookouts and assassins on both sides of the border.


While we are speaking about cartels, are you aware of the newest and fastest growing cartel?  Check out this article about The Jalisco New Generation cartel.


You might also take a look at El Sicario- The Autobiography of a Mexican Assassin.  I just finished the book and found that it did a great job portraying the life of a Mexican drug cartel hitman.



Taking Truth from the Dead – Newhall 45 Years Later


This week marks the 45th anniversary of “The Newhall Incident,” a gunfight where four California Highway Patrol officers were killed.  This gunfight single-handedly led to the “officer survival” movement of the 1970s, bringing much needed improvements to police equipment and training.  If you’ve never heard of the Newhall Incident, check out this article by my friend David Reeder.  If you want to learn more about this infamous gunfight, I would recommend the book Newhall Shooting – A Tactical Analysis by Michael Wood.



So – White People are Allowed to Riot?


Some quality commentary on the difference between the riots in Ferguson, Missouri and those that occurred this week at the University of Kentucky.  The author has a point.  Not all riots are the same.  Having differing tactics for differing event characteristics is the mark of good policing…not default evidence of a racist police culture.
