Social Distancing Card Posted on March 18, 2020 by Joe Via Ry. Boomershooters will get it. If you don’t, you might want to figure it out. Like this:Like Loading... Related Share
I figured out most of what is on that card. Only question I have is about the distances. Are they really talking about engagement distances of 2200M? I’d have to assume they are not using small arms?
Explains this particular card. The weapon system on this card is a TOW.
Nothing says “get off my lawn” like TOW-2
That’s very good for fixed or frequented positions, but also; carry a rangefinder. Keeping one in your pocket also works as a tool to learn better to estimate distances. Rangefinders are nice and small nowadays.
Know the angular size of the width of your thumb at arms length, for example also, or the length of an average car or the height of a man at various distances compared to the width of your pinky finger at arms length, etc. Simple subtension rules. These are the sorts of tools marksmen used before optical or laser rangefinders. The diameter of the moon (and the sun) is about 31 M.O.A. (arc minutes) from our point of view, and thus can serve as a fairly handy “calibrator in the sky”. If your rifle has a front sight, then you should its angular width as seen when the rifle is shouldered (or any feature which can serve to exhibit a consistent, repeatable angular size) etc., etc.
I have a device that I bought in 1982, called a “Telefix”. It is a scale with an adjustable window, that you hold a fixed distance from your eye and use to calculate distances of an object with a known size,or size if you know the distance using similar or proportional triangles. It has since disappeared completely from the internet, although you can find reviews of it from back in the day.
Knowing and remembering angular size of thumbs, fingers, and the Moon and your front sight seem better than using numbers from the Telefix and multiplying by known sizes, since there is a small risk of losing or breaking the Telefix.
And for practice, do you recommend a laser range finder?
