The Military Tools do not work when accessing from the Analysis tab Military Tools dropdown when Military Tools for ArcGIS 3.3 is installed on ArcGIS Pro 2.3.
There is a patch released to address this issue. Please have the user install and use Military Tools for ArcGIS 3.3.1. This is available from the solutions website, http://solutions.arcgis.com/defense/help/military-tools/. User needs to uninstall any previous versions of Military Tools prior to installing version 3.3.1. There is a known issue with core that the assembly cache folder does not get updated when installing a new version which is why an uninstall or install is required.
