A new version of the Study Guide for Testing to Staff Sergeant was posted on the official website on 1 February 2024. The new study guide is based on the 1 Nov 2021 version of the Air Force Handbook so the content of the study guide hasn't changed. However, the ADTC for the new 2024 study guide changed five sections (4B, 8B, 13C, 14D, and 14F) from testable to not testable. And one section (18A), which was not testable before, is now testable.

Each of the three testable sections in chapter four of the 23E5 study guide and the 24E5 study guide was converted to text and compared. There are no changes except that Section 4B is now not testable. The chapter four summary test for promotion to E-5 and the overall practice test for promotion to E-5 have been updated.







Notes on the Study Guide for Testing to Technical Sergeant, dated 1 November 2023

A new version of the Study Guide for promotion to E-6 was posted on the official website on 2 October 2023. The new study guide is based on the 1 Nov 2021 version of the Air Force Handbook so the content of the study guide hasn't changed. However, the ADTC for the new study guide changed four sections (4E, 13B, 14A, 14D) from being required for study to not being testable (for E-6). And one section (19A), previously marked as not testable is now testable.

To be sure that the content hadn't changed, each section in chapter four of the 23E6 study guide and the 24E6 study guide was converted to text and compared. There are zero changes except that Section 4E is now not testable. The Practice Test section was modified to match this new requirement.







Notes on the Study Guide for Testing to Technical Sergeant, dated 1 Nov 22

On 22 November 2022, the Air Force published a new version of the study guide for promotion to E-6, dated 1 Nov 2022, on their website. It replaces the study guide for promotion to E-6 dated 1 November 2021 for promotion test cycle 23E6 (15 Feb - 15 Apr 2023). This is an unusual action in that normally, the study guide issued in 2021 would be the source for study for test cycles 2021 - 2023. A cursory review of the new study guide revealed no major changes and appears to only correct the minor differences between the 2021 E-5 and E-6 study guides as noted below.

Note: In the new 2022 E-6 Study Guide, in the ADTC, Section 4B, Military Departments, was removed as a required section for study. However, the study guide includes Section 4B, Military Departments, and, in the REQUIRED LEVEL OF COMPREHENSION FOR DEVELOPMENT AND PROMOTION table at the top of Section 4B, it is identified as "B", indicating that it is required for study. Based on the fact that Section 4B is included in the study guide, we are assuming that the change to the ADTC in the new study guide was an error.



Differences between 2021 and 2022 E-6 Study Guides

4.1. Command Authority

Since the birth of our Nation, policies and directives have been made by civilians assigned to the military and to the executive and legislative branches of the government. Command authority is the established levels of responsibility for command, control, and communication throughout a chain of command. Responsibility and authority for the U.S. Armed Forces extends from the U.S. President, through the Secretary of Defense, through two distinct branches of command, and through each commander at every level in the branches of service. The various levels within the chain of command have different responsibilities and authority; however, each level in the chain is responsible for all lower levels and accountable to all higher levels.

Major Commands. Major commands (MAJCOM) are organized functionally in the United States and geographically overseas. A MAJCOM, as shown in Figure 4.3., represents a major Air Force subdivision having a specific portion of the Air Force mission. Each MAJCOM is directly subordinate to Headquarters Air Force. MAJCOMs are interrelated and complementary, providing offensive, defensive, and support elements. An operational command consists (in whole or in part) of strategic, tactical, space, or defense forces, or of flying forces that directly support such forces. A support command may provide supplies, weapon systems, support systems, operational support equipment, combat material, maintenance, surface transportation, education and training, special services, and other supported organizations. Within the Air Force MAJCOM structure, there are two specialized types of MAJCOMs: Lead MAJCOMs and Component MAJCOMs.

Group. A group is a level of command below the wing. Like the Numbered Air Force, a group is a tactical echelon with minimal staff support. A group usually has two or more subordinate units. A dependent group is a mission, logistics, support, medical, or large functional unit, such as a civil engineer group. Dependent groups may possess small supporting staff elements that are organized as sections, such as standardization and evaluation or quality control. An independent group has the same functions and responsibilities as a like-type wing, but its scope and size do not warrant wing-level designation. Groups will have a minimum adjusted population of at least 400 (200 for Air National Guard and Air Force Reserve Command), to include manpower authorizations, students, and a percentage of contractor workforces.

Notes on Air Force Handbook 1, dated 1 Nov 21, Chapter 4, Military Organization and Command


7 Feb 2022. The 2021 Air Force Handbook is not available and may not exist. The E-5 and E-6 Study Guides were released and posted to the official Air Force website (https://www.studyguides.af.mil/) on 1 Feb 2022. This website was updated using the content from the E-6 Study Guide under the assumption that both study guides contained the same content. However, there are differences between the two study guides as noted below. Questions related to these differences have been removed or edited, as necessary, to avoid conflict between the two versions and ensure accuracy.

The phrase, "Air Force", was replaced globally by "USAF" in the E-5 Study Guide.

Paragraph numbering for Section E, Air Force Structure, is different: E-5 Study Guide has 4.14., 4.15, and 4.16. E-6 Study Guide has Section E as 4.10., 4.11., and 4.12.

Chain of Command. By statute, the chain of command runs from the U.S. President, through the Secretary of Defense, to the Combatant Commanders. For all forces not assigned to the Combatant Commanders, the chain of command runs from the U.S. President, through the Secretary of Defense, to the Secretaries of the military departments. When forces are assigned to the Combatant Commanders, administrative control over those forces still typically flows through their respective service branch. Note: A provision of the Public Law 99-433, Goldwater-Nichols Department of Defense Reorganization Act of 1986, 1 October 1986, permits the U.S. President to authorize communications through the Chairman of the Joint Chiefs of Staff, placing the Chairman in the communications chain of command.

Air Force Space Command.
Air Force Space Command (AFSPC) was activated as a MAJCOM on 1 September 1982, is headquartered at Peterson Air Force Base, Colorado, and is one of two Air Force Components of U.S. Strategic Command. AFSPC's mission is to provide resilient and cost-effective space and cyberspace capabilities for the Joint Force and the Nation. AFSPC organizes, equips, trains, and maintains mission-ready space and cyberspace forces and capabilities for North American Aerospace Defense Command, U.S. Strategic Command, and other combatant commands around the world. AFSPC spacelift operations provide services, facilities, and range safety control for the conduct of 18 Department of Defense, National Aeronautics and Space Administration, and commercial launches. Through the command and control of all Department of Defense satellites, satellite operators provide force-multiplying effects through continuous global coverage, low vulnerability, and autonomous operations. Satellites provide essential in-theater secure communications, weather and navigational data for ground, air and fleet operations, and threat warning. Maintaining space superiority is an emerging capability required to protect space assets. New transformational space programs are continuously being researched and developed to enable AFSPC to stay on the leading-edge of technology. Collectively, AFSPC units are the warfighting organizations that establish, operate, maintain, and defend Air Force networks and conduct full-spectrum operations. Made up of cyberspace professionals, a diverse blend of career fields ensure the Air Force and Joint Force ability to conduct operations via cyberspace. Overall, more than 35,000 space and cyberspace professionals are assigned to AFSPC at 134 locations worldwide. More than 4,600 men and women conduct or support 24-hour cyberspace operations for 24th Air Force units. In addition, more than 10,000 Air National Guard and Air Force Reserve personnel directly support the AFSPC cyberspace mission. Following the establishment of the U.S. Space Force as a new Armed Service within the Department of the Air Force, the SECAF designated AFSPC as Headquarters USSF, and re- designated 14th Air Force as the Space Operations Command (SpOC) -one of three Field Commands in the USSF. Effective October 21, 2020, SECAF re-designated the former AFSPC staff organization at Peterson Space Force Base as HQ SpOC. This re-designation aligned the Field Command responsibility for organizing, training and equipping and presenting USSF forces to the staff and commander responsible for executing this mission.
