  SECTION III – INTELLIGENCE CAPABILITIES
  1-54. The intelligence warfighting function executes the intelligence process by employing intelligence
  capabilities. These capabilities comprise personnel, systems, and supporting technology—all of which are
  maintained, trained, and employed to conduct intelligence operations to facilitate situational understanding
  and provide intelligence support to targeting.
  1-55. The intelligence staff (chapter 5) and MI units/organizations (chapter 7) collaborate closely to ensure
  the commander and staff receive all-source and single-source intelligence—the building blocks by which the
  intelligence warfighting function facilitates situational understanding and supports decision making and
  targeting. The intelligence warfighting function receives information from a variety of sources. Some of the
  intelligence sources are commonly referred to as single-source collection. Single-source collection is
  employed through intelligence operations (the means of information collection performed by MI units), or it
  is one of the closely related operations (complementary capabilities). Intelligence PED capabilities are also
  necessary to process information and prepare it for subsequent analysis or target nominations. The
  intelligence produced from access to information from all (or several) of those information sources or from
  single-source intelligence is called all-source intelligence.
  ALL-SOURCE INTELLIGENCE
  1-56. Army forces conduct operations primarily based on all-source intelligence assessments and products
  developed by the intelligence staff. In joint doctrine, all-source intelligence is 1. Intelligence products and/or
  organizations and activities that incorporate all sources of information in the production of finished
  intelligence. 2. In intelligence collection, a phrase that indicates that, in the satisfaction of intelligence
  requirements, all collection, processing, exploitation, and reporting systems and resources are identified for
  possible use and those most capable are tasked (JP 2-0). For the Army, all-source intelligence is the
  integration of intelligence and information from all relevant sources in order to analyze situations or
  conditions that impact operations (ADP 2-0).
  ALL-SOURCE ANALYSIS
  1-57. The fundamentals of all-source analysis comprise intelligence analysis techniques and the all-source
  analytical tasks: perform situation development, conduct pre-mission analysis of the OE, perform IPOE, and
  provide intelligence support to targeting.
  1-58. The intelligence staff determines the significance and reliability of the incoming information by
  comparing it with current intelligence holdings; subsequent analysis and evaluation assist the intelligence
  staff in determining changes in threat capabilities, vulnerabilities, and probable COAs across the domains
  and dimensions of the OE. The intelligence staff supports the integrating processes (IPOE, information
  collection, targeting, risk management, and knowledge management) and the integration of intelligence
  support into operations by providing all-source analysis of threats, terrain and weather, civil considerations,
  and other significant aspects of the OE. This support also accounts for human and information dimension
  effects within the operational and mission variables.
  1-59. All-source intelligence is used to develop the intelligence products necessary to aid situational
  understanding, support the development of plans and orders, and answer intelligence requirements. Although
  all-source intelligence takes longer to produce, it is more reliable and less susceptible to deception than
  single-source intelligence.
  ALL-SOURCE PRODUCTION
  1-60. Fusion facilitates all-source production. For Army purposes, fusion is consolidating, combining, and
  correlating information together (ADP 2-0). Fusion occurs as an iterative activity to refine information as an
  integral part of all-source analysis.
