Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
What is the GTA 5-2-12?
The standard-issue coordinate scale and protractor used for military map reading, covering common map scales for plotting grid references and bearings.
Which map scales does it cover?
It carries the standard scale set for military topographic maps. Check the scale printed on your map matches one on the protractor before plotting.
What else do I need to plot a grid?
A topographic map, a compass, and something to mark with. Pace counter beads help you track distance travelled between plotted points.
