Hey now! I resemble that remark. At least the LT part of it. BTW, the equation is not necessarily wrong but that is why PSG's carry a compass too...and usually don't stay within ten yards of a PL. They're so shiny and new that they cancel any Grid to Magnetic adjustment. (Or maybe they just forget to do the declination before moving)

In full disclosure, I was seven years infantry before OCS, so when snap judgments were made seeing my glaringly shiny butter bar, the subdued tabs and unmistakable pumpkin patch on my left blouse pocket tended to stop the snickers fast. lol.
