RPG-75 Guide
From COALITION Wiki
This launcher is fairly simple. It does not zero with your zeroing keys. However, it does come with a simple calibrated sight. Simply line up the wire marked with the distance you need, and fire.
The sight does include A simple range finder, however it seems ineffective in Arma. Probably due to incorrect modeling. Safe to say, if A tank fits perfectly in the 250m slot, its actually at 300m. If it fits in the 300m slot, its at 500m. The 100m range finding method shown in the document below seems to work if the tank fits between the 300m wire and the bottom of the sight.
Top: Target at 300m
Bottom: Range finder on M1A1 at 300m. Built in range finder cannot be trusted in arma.
