After 70 or so kilometers of travel, humping a 100 pound large Alice pack over mountainous terrain for the previous several days and living on minimal food I was a walking zombie. I had just finished navigating my small element to a road intersected by a large river, “Sgt this is our point.” Our Cadre looked us over then took off walking down the road. The concept was foreign to us, we hadn’t walked trails or roads for the past week. We followed after him at a trot our Alice packs squeaking. “If we move quickly we might leave today,” the Cadre said in a nonchalant manner. Elation surged through me. Another phase down in SERE Specialist Training. We hit our rally point a half mile down the road and found some other elements from my class leaving in a truck with very minimal gear and sour expressions. Psychological warfare at its finest. We were rolling directly into a 4 day solo evasion living exercise.
I cannot recall the exact list of items I was allowed to take with me on my solo evasion exercise but it was something akin to the following; USAF Survival Knife, Leatherman, 8-gores from a C-9 emergency parachute (common in ACES II ejection seats), Line kit (10 lines of 6 foot 550 cord, and 10 lines of 15 foot 550 cord), Sleeping bag and bivvy, And several other misc items. We’d had a similar exercise during SERE Specialist Selection though less intense. The point of these exercises is that in a survival situation whatever you have on you is all you have. Improvisation is key to ensure your survival in many cases.
You need to first determine a need. When I first got out to my area for solo survival during SERE Specialist Selection I had little cover from the sun and would likely expire from heat exhaustion unless I got a shelter erected to protect myself. Once the need is determined you should inventory those possessions that you have and also look at the environment to see what it has to offer. Your manmade items are limited, however nature provides a variety of resources available to you in order to build a shelter. In certain tropical climates for example banana leaves can be used very effectively to shield you from the rain. Once you’ve seen what you have and what nature offers you need to select an option that is going to be a good use of time, materials and energy. If I find myself in terrible weather with pelting rain and I’m going to make a more expedient, simple shelter than if I find myself in a survival situation in the early afternoon in good weather. The same goes for the situation I found myself in after rucking through the mountains. I was exhausted. Be realistic with how much energy you can spare and don’t try and make yourself a mansion.
Make sure when you plan your shelter you make something that is safe and durable. A shelter that collapses on you and kills you is a hell of a way to go. In general there are two types of materials you can use to make a shelter; permeable and non-permeable to water. The parachute I used to make my shelter during selection was a permeable material. To help ensure that water won’t get through you can do two things.
