The Tactical Assault Kit (TAK) is a tool used by the Department of Defense (DoD) for mission planning, geospatial, Full Motion Video (FMV), and system administration. It reduces the operational footprint from a tactical laptop to a commercial mobile device. The geospatial engine and communications component support DoD and commercial sector standards. The Software Development Kit enables any partner to develop mission-specific capability or contribute to the advancement of the baseline. Data can be pre-loaded into ATAK or downloaded from the network when available.

ATAK-CIV is the civil use version of ATAK. It includes online and offline mapping, collaborative mapping, location marking, sharing, history, chat, file sharing, photo sharing, video sharing, streaming, navigation, elevation tools, heat maps, computed contour maps, viewsheds, routes, hashtags, sticky tags, range, bearing, and other measurement tools, network-aware geofences with triggers, "Bloodhound" destination tracking, team emergency beacons, customizable toolbar, radio controls and integration, photo to map capability, casualty evacuation tool, icon support for a wide variety of First Responder missions, 3D perspective, and ability to display 3D geospatial models. ATAK-CIV is open source.

To use ATAK, the system requirements include Android 5.0 (API 21) or later, a graphics processor that supports GLES 3.0, and no specific requirements for storage, memory, or processor. Recommended hardware for optimal experience includes Samsung S9 equivalent hardware or newer for a phone and Samsung S2 equivalent or newer for a tablet.

TAK CORE is a cross-platform layer that includes functionality that is common to all TAK applications. It focuses on capabilities such as networking, geospatial data processing, geospatial data visualization, and geospatial data management.
