The Tactical Ruler Echelon UA is a tactical tool from the Ecopybook Tactical® brand.

It is made from anti-glare material, which minimizes the risk of detection. The importance of non-glare stationery has significantly increased with the rising use of UAVs for aerial reconnaissance. Traditional tactical rulers often have a glossy surface that reflects sunlight. To minimize these reflective issues, it is recommended to use anti-glare rulers. These rulers are made from durable, transparent, and flexible polymer materials.
