Lessons Learned Division:  Actual Operations Branch

The Lessons Learned Division is composed of two branches: Actual Operations and Combat Training Center.


The mission of the Lessons Learned Division is to process and analyze observations and information from a variety of sources, and to produce literature in a variety of media which contain lessons learned and TTP.


To be effective, the lessons learned process must be comprehensive. Therefore, units and individuals play a tremendous role in providing a knowledge base for the whole of the Army. CALL continually solicits and receives observations, lessons, articles, and information from the Total Force which enables others to learn and refine unit training. If the observations and lessons that you learn from CALL publications and electronic media assist you in accomplishing the mission, then the lessons learned process is working effectively. Individuals and units that have lessons and information that can assist other units to do the job correctly the first time should forward their input to CALL. CALL will acknowledge receipt and work with the author(s) to refine the content into a publishable form. CALL can edit, format, and provide the layout.

It is everyone's responsibility to minimize losses and accomplish the mission to standard the first time. There are numerous means to contact CALL. They are identified and explained within this handbook.


CALL receives input from a variety of sources and in many different forms. For large or complicated observation collection, CALL organizes a Combined Arms Assessment Team (CAAT). When a CAAT is used, the analysis process usually begins with a subjective analysis accomplished while in theater by CAAT members and the CAAT team chief. Simultaneously, a CALL analyst at the Center reviews observations and raw data received from the CAAT for content, rewriting if necessary, and refining the input. The analyst also provides comments and recommendations back to the collection team for clarification and validation. This exchange of information reduces the amount of time necessary to provide feedback to deploying units and the U.S. Army.


Input to the Lessons Learned Division can consist of information in differing formats and perspectives. As the CAAT-Analyst relationship describes, preliminary screening or analysis is conducted by the analyst to determine the relevance of observations collected by a CAAT. However, input to the Lessons Learned Division can include articles devoted to lessons and general information that may have importance to the U.S. Army such as tactics, techniques and procedures. If the collected data is considered relevant and valuable to the U.S. Army, it can be manipulated, edited, and formatted as necessary and placed in various CALL products for dissemination. Input to the Lessons Learned Division can be both active and passive and subjective and objective. To provide the field with timely information, lessons, and tactics, techniques and procedures, CALL publishes a wide variety of products. The following provides a short explanation of several CALL products.

Newsletters: A Newsletter is a publication that addresses a specific subject (i.e., Humanitarian Assistance, Civil Disturbance).

CTC Bulletins, CTC Observations and Trends Products: These products are periodic publications that provide current lessons/TTP and information from the training centers (see Combat Training Center (CTC) Branch Section).

Special Editions: Special Editions are newsletters related to a specific operation or exercise. Special Editions are normally available prior to a deployment and targeted for only those units deploying to a particular theater or preparing to deploy to the theater.

News From The Front! Bulletin: This bulletin is a bi-monthly product that contains information and lessons on exercises, real-world events, and subjects that inform and educate soldiers and leaders. It provides an opportunity for units and soldiers to learn from each other by sharing information and lessons with the Total Force.

Training Quarterly: Accessed from the CALL Homepage. The Army's first on-line publication. It is focused at TTP for brigade and below.

Handbooks: Handbooks are "how to" manuals on specific subjects (i.e., rehearsals, inactivation).

Initial Impressions Products: A product developed during and immediately after a real-world operation (Bosnia, Vols: I, II, III/IV) and disseminated in the shortest time possible for follow-on units for use in educating personnel and to support training prior to deployment to a theater. Training products (i.e., vignettes) may also be produced to support the follow-on unit to focus training activities.

It is the analyst's responsibility to develop all collected data into a form that is meaningful, provides discussion, supports an exchange of ideas, and enables a reader to enhance performance or facilitate individual and unit training and operations. CALL serves as a conduit between sources of information and the users of that information.
