The Defense and Intelligence guide book of the ArcGIS 10 Help describes the defense and intelligence related tasks you can perform in the most recent release of ArcGIS. For example, Military features describes how you can represent military features in ArcGIS; Support for MGRS in ArcGIS describes the ways you can use the Military Grid Reference System in your maps; Data management for military data describes ways you can simplify your ArcGIS work with NGA data.
Other parts of the Help system also cover areas of interest to Defense and Intelligence ArcGIS users. For example, Image Analysis Window shows you how to enhance and apply functions to images and mosaics. Enabling time on your data describes how to work with time-sensitive information in the GIS. A quick tour of creating tools with ModelBuilder shows you how to create analytical sequences that can be replicated and shared.
The Defense and Intelligence blog provides information from the ESRI Defense and Intelligence team on defense-related templates and resources posted after the latest release of ArcGIS. It also includes tips and tricks.
The Defense and Intelligence forum is a place to ask other defense ArcGIS users and the ESRI Defense and Intelligence team questions that might be of interest to all users. It is also a place to discuss your experience with templates and tools designed for military and intelligence users.

The Defense and Intelligence gallery contains templates to help you create Defense and Intelligence maps and applications. Basemap templates provide a framework and guidelines for loading raw data from mapping agencies into more useful GIS maps. Application templates provide tools that help you automate a task, such as importing GPS data from patrols, or identifying key terrain. Military feature templates provide geodatabase schemas and symbology for creating features that comply with MIL-STD 2525C.
The Defense and Intelligence Videos gallery contains videos created by the Defense and Intelligence team and by other groups at ESRI on topics of interest to Defense and Intelligence GIS users.
