 commanders. The systems developed feature advanced predictive capabilities to enable computers to efficiently and accurately predict possible future scenarios, based on an analysis of the current situation, in order to give army commanders a better view of possible outcomes for their decisions

Deep Green is composed of four major components:

• Blitzkrieg -- Battlefield model which analyzes current situation and determines possible future outcomes for use in planning. When a plan is presented, Blitzkrieg analyzes the plan to point out possible results of that course of action to the commander. Blitzkrieg itself does not do planning, it merely determines the likely results of a plan formulated by a human commander.
• Crystal Ball -- Performs analysis of possible futures generated from blitzkrieg, and determines the "best" choices by measuring flexibility, usefulness, and likelihood of each. It picks the best of these choices and presents them to the commander. Also updates model of battlefield situation with information pulled from the field. This might include reports from soldiers, through a program similar to the Communicator program that was developed under the Information Awareness Office
