We have a strong requirement to be able to easily calculate the distance and bearing between two points. The military analyst extension, discontinued with Arc 10.2, had the Geodesy calculator which interactively calculated distance and bearing between a start and end point. Calculating a bearing distance in Defense Mapping, under the Production Feature Builder toolbar, works awkwardly, but unfortunately doesn't have the mils unit for bearing. One of our requirements involves the training safety of military personnel using field artillery - not insignificant. We need a simple interactive tool for general users that restores this functionality.
