To those who want to try their skills. What is it, and why it is significant?
The Answer.
Yes, it is a template. It is called The Officer Ruler, and it is--it is for the proper illustration of tactical and operational maps and presenting the Commander's Decision to higher-ups. Most kids in the USSR had this ruler and you could buy it pretty much anywhere. It is all about topography. Naval rules look different, and they are parallel rulers.
