What is a cache? Caches are prepositioned resources put in place to support a future activity. Classically we "visualize" them as buried treasure but they don't have to be buried, and we will cover that a little later in this article. Having been to a Special Forces school for this, I'm happy to say this subject is one of my favorites and an area that I have plenty of real world experience. The challenge of this article will be keeping it unclassified, so if there seems to be a "gap" in the flow of the article, accept my apologies up front I'm trying to make everyone happy... Caches have been used for centuries, there's nothing new about them but in todays fast paced disposable world they are usually overlooked as lacking imagination or to time consuming. Of course the big army (or military) as a whole doesn't really use caches, but a cache system doesn't make sense for our modern army. They come complete with supply trains and never really know where the next operation will take place. They are designed for mobility. You however are not.
You KNOW where you will be staying, working and traveling. A cache network would fit easily into the busiest modern schedule and as we will discuss lighten your bug out loads considerably. Caches are the difference between a 100lbs Bog out Bag (BoB) and a 20lbs BoB. Use caches to offset your emergency weight and have enough that you can afford to lose a few to the elements. Caching is a process not a singular event. Why use them? Caches will drastically offset the amount of weight and equipment required to get from A to B on any map. If established correctly, you could have a cache set up at all of your major check points and if you don't need to contents of the cache, bypass it and save it for later. If you have ever wondered how commandos get away with traveling so light, its because we aren't just moving to a safe area I'm admitting we are cheating, and picking up food and ammo along the way that someone else buried before hand. Like a magician, the trick isn't magic, its the assistant who skillfully positions the tools needed ahead of time when no one was looking.
[gallery type="rectangular" orderby="rand" ids="2365,2366,2367,2368"] Site selection criteria. Its not good enough to just pick a gnarly oak tree and have at it. In theory you should have dozens of these located all over the place so site selection criteria has to take on a consistent, and more primary role as you develop your network. Consider:
Types of caches. I like to build caches based on themes so that's what ill discuss in this article. Most of my caches are simple food and water 24 hour kits, small and easy to hide. I have 1 large cache, that remains unmarked and only I know where it is that contains everything I need to start over... I bury this early and let it season in the elements. Consider:
You can build and camouflage caches out of anything, you're limited only by your imagination. Just make sure they are double weathered sealed. Consider using packing grease when storing working "metal" parts for long periods of time and using metal containers for water. Metal containers don't leak into the water like plastic bottles do. How to organize them into usable networks. Its all about the mapping. I break my mapping down into useable blocks that are easy for family members to follow and understand. There are 3, maybe 4 basic sketches you need to learn:
Here's an organization example of how I set up my cache mapping:
I would keep all of these in a book and even supplement the data with a Google earth maps overlay. Ideally when I forward a cache I want the information as simplified as possible yet accurate. This way in a pinch I could simply "text" it to someone and send them on their way.
Under this organization I can group my caches and maps into zones, and maintain an underground supply network that supports multiple family members in different locations, perhaps a child in college and so on. [gallery columns="2" size="medium" type="rectangular" ids="2353,2355"]
Mapping is the trickiest part of all of this. Caches are aren't any good if YOU are the only one who can use them. But for OPSEC or data reasons you may not have access to accurate enough mapping to make this work. So make your own! [gallery type="rectangular" ids="2360,2361,2362"] The trick to this is finding the right amount of detail with out over crowding your work. Practice this amongst your own group to see what I mean. Have one person draw a map to an unknown location, and another person navigate to it with out any assistance. Then you will see how your assumption over the obviousness of a particular reference point may not be as obvious as you previously thought. There is an art to it and it must be learned and rehearsed. We wont go to far into mapping in this article, its an article all its own but we will write it up as an addition to this cache piece.
Of course here at CAGmain we offer a wide variety of classes and that includes how to cache. Caching is a hybrid of field craft, administration and art its not just bury MREs in the woods for a rainy day. Play with Geocaching and get a feel for the venue and see what other folks have done. Its fun and family oriented I think you'll like it. Click this link to learn more! As always thank you, and please ask questions!
Hemostatic Gauze Vs. Non-Hemostatic Gauze... There are many types of gauze on the market to choose, from standard gauze rolls to different types of "Hemostatic gauze", which are impregnated in substances to help stop bleeding. Without understanding the differences between a package of compressed gauze, to Combat gauze, Celox-gauze and Chito-gauze, how they work, or even if they work, it can be difficult to decide which one is right for you and your medical kits. Here's the breakdown:
Plain (Non-Hemostatic) Gauze: Often called Kerlix, and coming in "Z-fold" or "S-rolled", or even compressed to take up less space, This is a must and a minimum. While this gauze certainly is not as good as the hemostatic gauzes in terms of controlling severe hemorrhage , It's inexpensive and versatile use make it a must. This isn't just for packing a bleeding wound that a tourniquet can't reach, it can be used as simple bandaging, dressings, stabilizing such as a sling and swathe and so much more. For the low-cost, it's a stepping stone towards hemostatic gauze. I recommend at least 2-3, and more in your house/truck kit, for those areas on your body where a tourniquet can't stop the bleeding, or for a little pressure in an extremity that is not a severe enough bleed to warrant a tourniquet. [gallery size="medium" type="rectangular" link="none" orderby="rand" ids="2327,2328,2329"] Hemostatic Gauzes - For arterial bleeding, don't risk having a non-hemostatic gauze as your Primary choice, you and your loved ones deserve the best shot at survival. What you do for bleeding control for the first few minutes is similar whether you are in an austere environment or 911 is just a few minutes away... If you don't get this bleeding stopped, it will eventually stop when the patient runs out of blood. Unlike previous generations of hemostatic gauze, these do not generate heat or burn. Here's your choices, and how they work:
[gallery type="rectangular" size="medium" ids="2338,2339,2340"] These are in no particular order, and I'd recommend all 3 as a good decision. While the Military recommends Combat Gauze as #1, their demographic is healthy young soldiers who likely don't have poor clotting factors. Even then, blood loss can cause hypothermia and ruin their clotting factors, making Celox or Chito-gauze an option as well. Now that you know why and how, you can make an educated purchase. Personally im a fan of Chito-Gauze, but I'm also a reasonably trained medic...
A product is only as good as your training, so if you leave it on the shelf, it won't live up to it's potential in a stressful situation. Have a couple non-hemostatic gauze as "trainers" to practice wraps and packing wounds as free drills to keep sharp. You do dry
A consideration for austere management of anaphylaxisAnaphylaxis can be a scary encounter even when 911 is a few minutes away. In Austere medicine, where patient evacuation is delayed, not on it's way, or you are the medical professional sitting on this patient, a serious situation just became worse. When you give your initial intramuscular injection for anaphylaxis, there is about a 20% chance you patient may need another dose, but you only had one Epi-pen... What now?
A Consideration for Austere Management of Sucking Chest WoundsToday we are going over one of the leading preventable causes of death on the battlefield: Tension Pneumothorax. Don't get hung up on the medical words, we'll have you understanding how to and why you treat a gunshot wound from Neck to Naval in no time. The battlefield sets the example for first line care because we learn from our mistakes and translate them into the civilian care. The front line medics are expected to uphold the standard in Austere Medicine where they don't have an ambulance but just the supplies on their back. However, not just the Combat Medics on the battlefield are trained, but non-medical professionals are being taught how and why to save lives in first aid. This is where the Austere Medical provider comes in, when 911 is not coming and you have to treat and get them to the next level of care by yourself or with the assistance of your Emergency Action Group. Before we can go over how to treat, we must understand "why" we are treating:
⦁Normal Saline: In an Austere environment, we don't have the luxury to stockpile Normal Saline and do an irrigation as clean as we'd like in a hospital room. It's simply not cost effective, or worth its weight in a Rucksack as far as I'm concerned. Many studies have come out referencing potable water's effectiveness rivaling, if not exceeding the effectiveness of N.S.
⦁Purified Water: If you have enough stored, I'd recommend "Pool Shock" granular calcium hypochlorite over Bleach. Both work just fine, however Bleach has a short shelf life of around a year as opposed to nearly a decade with properly stored pool shock. While boiling water is the best for purifying drinking water, you may not have those capabilities for wound irrigation on you.
⦁ Non-Potable Water: Water that is not safe for drinking or has not been tested or purified is still good to go for wound care if you have to in an austere environment. The benefits of a flush from a non-purified water source outweigh the risks. The benefit with using a local body of water or other source is you are not as worried about wasting a finite resource and can afford to be as aggressive as needed.As you can see, it's not a big deal about how purified the water is or what is in it. You want to use a ton of water and most importantly you want to create enough pressure. I recommend you act like you KNOW something is crawling around on the surface, so you don't underestimate how much you need.

This is how I rig my personal BoBhttps://youtu.be/NBqnSyTp9Rg If you don't know how to use it, why carry it? It's just weight at that point and during the emergency is the worst time to learn. Start thinking a little more Spartan, and slim down your kit to BARE ESSENTIALS. Weight is brutal...Weight is brutal... We need to stop making these comfort packs and calling it a survival rig. Fact is there's no "list" so each mobile kit you produce MUST be tailored to your individual needs and circumstances. In Special Operations we will build our kits to fit the mission profile and evasion plan we going to exercise. There is no bag we grab and call it good to go.
