Firstly, high tech combat is modern warfare. This involves combined arms battle groups, satellite communications, automatic weapons, aircraft carrier battle groups and maneuver warfare. This is warfare utilising modern technology. It is warfare waged by states. It is the methods and tactics used against the Taliban in the mountains of Afghanistan.
In comparison, low tech combat is combat using low tech, or no technology. It is up close and personal. It can be unarmed combat or it can utilise basic impact weapons such as a stick or marble ash tray. It can be combat using edged weapons such as a knife or screwdriver. It can be one on one or one against many. It can be a combination of the above. It is the combat engaged in on the streets and in homes around the world.
A robbery or fight out the front of a pub are all elements of, but not low tech combat in its entirety. Implementing home security measures is engaging in low tech combat as is not opening the door at night because the person through the peep hole just doesn’t look right and the story doesn’t sound right. The deathmatches of the old Filipino masters is also. All of these and more are elements but not complete elements of low tech combat.
It also involves activity BEFORE it gets physical. This is things such as awareness, avoidance and manoeuvre. This is a large part of high tech combat as well. The earlier you detect a threat the better you can prepare for combat or facilitate avoiding it altogether. That is the ultimate aim in low tech combat. Avoiding it. This is the highest level. The best soldier is the one who detects the enemy before they detect you. The same applies in low tech combat.
Low tech combat is a large field with many opportunities for learning. It is considered best practise to learn systems with a crossover benefit to other areas such as MMA, RBSD and simple Filipino weapons systems as well as study the theoretical aspects as well.
