I bought a POSP 3-9x42 optic for my kalashnikitty and am having some difficulty discerning how to use the reticle. The manual that came with it is entirely in Russian so it's of no use and I understand that the rangefinder in the lower left is a scale for a 1.5 meter object at various distances (starting with 200m out to 1000m). My question is three fold. What standard object were the russians thinking of to use as the 1.5meter standard. It used to be 1.7 or 1.8meters, roughly the size of your average man. I don't know what to base a slightly-smaller-than 5ft scale off of... (I doubt even a malnourished russian soldier would be that short) the horizontal hash marks are also used to help find scale, but I don't know what to reference them to. 1m? .1m? How are the verticle chevrons meant to be used?
