The French Army provides us with the first examples of Inspectors General (IG) in Western culture. In 1668, an IG of infantry and an IG of cavalry were appointed, with the principal duties of reviewing the troops and reporting to the king. Louis XIV expanded the system to include geographical inspectors. They examined everything within their sphere of influence. Soon, military inspection became an essential aspect of all modern armies.

1775 - 1783

The U.S. Army Inspector General System was born during the Revolutionary War. The Continental Army, when formed in 1775, was a disorganized array of militia from different states, with no uniformity in organizations, procedures, drills, appearance, or equipment. The Continental Army's leadership was not comparable to the good, solid officer leadership of the British Army, and General Washington was not satisfied with the training and readiness of his diversified forces.

By the time of the American Revolution, the appointment of inspectors, at least in functional areas, was an established routine in European armies. The tactics of the day, volley fire and massed bayonet charges, required stern discipline and extensive drill and training. It followed that commanders needed a close look at the units and their readiness.

On 29 October 1777, General Washington met with 14 general officers and decided among other things that an IG for the Army was desirable. The IG would superintend the training of the entire Army in order to ensure troop proficiency and common tactics. He would be the commander's agent to ensure tactical efficiency of the troops, that of tactical competence. The duties envisioned were those of a "drill master general" or a "muster-master general."

At the same time, the Continental Congress recognized the need for an IG to provide it with information concerning a significant public investment. Therefore, the Congress understandably wanted an agent in the Army to help in accountability for the military investments. It also wanted assurances the military would remain subordinate to its authority. This parallel IG requirement created tension between the military and the civilian authorities. General Washington's preference for an IG answerable only to the Army chain of command prevailed, and subsequently IGs were ordered to report to the Commander in Chief. However, the tension created by a dual requirement for information continues even today.

On 13 December 1777, Congress created the Inspector General of the Army. The Congressional resolution directed that the IG would:

  • Review the troops
  • See that officers and Soldiers are instructed in exercise maneuvers established by the Board of War
  • Ensure that discipline be strictly observed
  • Ensure that Officers command properly and treat Soldiers with justice

The first Inspector General of the Army was MG Thomas Conway. Conway, an Irish Soldier of fortune, resigned shortly after his appointment because he couldn't get along with anyone in the American Army, to include General Washington.

The first effective U.S. Army Inspector General was Baron Frederick William Augustus Von Steuben. Von Steuben was a former captain in the Prussian Army. He was recruited for the American Army in Paris by Benjamin Franklin in 1777. Franklin recognized that quality of Von Steuben but was concerned that Congress wouldn't accept only a captain for such a position of responsibility. So Franklin "doctored" Von Steuben's resume in order to present him as a former lieutenant general, a grade he knew would be acceptable to Congress.

Von Steuben was accepted as the Inspector General of the Army on a trial basis by General Washington. He reported to duty at Valley Forge in February 1778. He spoke no English but learned quickly and impressed everyone with his hard work to improve the training, drills, discipline, and organization of the Continental Army. In May 1778, he was officially appointed Inspector General of the Army with the rank and pay of major general. Congress also appointed two ranks of inspectors general under the IG, providing us the first IG organization.

Many of the Continental Army's regimental colonels resented bitterly the efforts of the IG, whose duties as outlined by Congress included "to report all abuses, neglect and deficiencies to the Commander in Chief." It was Von Steuben's character, tact and genius that overcame a great deal of this resistance and as such, set the precedent for the manner and behavior for future IGs. MG Von Steuben is recognized as the "Father of the Inspector General System," and significantly influenced our Army's ability to fight and win.

1783 - 1900

The size and influence of the IG within the Army rose and fell, at times dramatically, during the 18th and 19th centuries. This was caused by Army strength fluctuations, changing personalities, and philosophical approaches to doing business by the senior Army policymakers of that era. During the 1790s, the IG was second in command of the Army. For a period after 1800 the IG duties were relegated to the Department of the Adjutant General and there were several times the position of IG was eliminated altogether.

The Act of 3 March 1813, which reorganized the staff of the Army, established the IG Department though it would not be until 1878 that the Department became a formal part of the Army organization. In addition to an IG, the act provided for eight inspectors general and many assistant inspectors general. These inspectors general did tasks that were very inconsistent with those of a present-day IG. This mix of duties was caused by not having a centrally developed doctrine that clearly defined the role of the IG.

How commanders used the IG improved greatly following the Civil War, when the War Department published an order defining the duties of the IG. In 1876, the Secretary of War directed the Inspector General of the Army to report to the General of the Army on all subjects pertaining to military control and discipline and all "field IGs" to report directly to the unit commanding general (CG). This directive placed IGs under the local CG's control for all matters. An IG was no longer a "spy" from a higher headquarters. This relationship continues today.

1900 - 1949

The greatest hindrance to IGs in inspecting the "old" Army was the dispersion of its force across the globe. After 1898, Army troops were scattered around the world, occupying Caribbean Islands and trying to suppress the growing rebellion in the Philippines. By 1900, IGs were inspecting all regiments deploying to the Philippine Insurrection and establishing a systematic inspectorate in the islands. The IG duty to inspect units deploying for combat overseas resurfaced during World Wars I and II, the Korean War, Vietnam, Grenada, and Operation Desert Shield/Storm.

From after World War I unit 1939, the number of IGs in the Army changed very little and IG duties remained stable. By 1940, all subordinate commanders down to and including divisions were allocated an IG under their direct control to conduct inspections and investigations as needed within their respective commands. By 1945, there were about 3,000 IGs serving with the Army around the world.

The IG mission grew in importance and scope during World War II and this trend continued into the postwar Army. Of particular note was the emergence of the assistance function as we know it today. The rapid draw-down of the Army from about 9 million in 1945 to a few hundred thousand in 1946, caused the IG to respond to thousands of requests for help from Soldiers being released from the Army (many because they weren't being released quickly enough).

1950 - 1959

The statutory basis for the current IG system comes from the 1950 Army Reorganization Act. This reorganization replaced the IG Department with The Office of the Inspector General of the Army (OTIG). The Inspector General (TIG) was responsible to the Chief of Staff, Army and responsive to the Secretary of the Army. The reorganization charged TIG with inquiring into and reporting upon the discipline, efficiency, and economy of the Army. Specifically, IGs were to focus their effort on training and combat readiness.

In 1952, OTIG initiated an orientation course for officers selected to be IGs. Prior to this there was no specific provision for the formal instruction of IGs, although the old IG Department had maintained and distributed instructional material to each IG in the form of inspection and investigation guides, handbooks, and other procedural material.

A legal case in 1953 resulted in the classification of IG data as having restricted access and use. IG investigations and reports were declared "privileged" as a matter of law. As such, they could not be used as evidence in judicial or other proceedings, except as specifically authorized by the authority ordering the investigation or higher authority.

The qualifications for IGs were first formally codified in 1957. Army Regulation (AR) 614-100 stated only the highest caliber of Army officers should be detailed as IGs and should meet the following minimum qualifications:

  • Mature with broad military experience.
  • Have not previously completed a normal three year tour as an IG.
  • Moral and personal traits which are necessary for a position of dignity and prestige.

The mission to conduct the indoctrination course for all officers newly detailed as IGs was transferred from the Office of the Inspector General Inspection Division to a newly established Field Services Division on 5 November 1956. The course, for CONUS based officer IGs only, was increased to three weeks (one week inspections, one week investigations and one week procurement), averaged 53 students a course, and was taught four times a year. The frequency of presentation increased to six by FY 58 and expanded to allow selected civilian employees and NCOs assigned to IG offices to attend. Also in FY 58, a modified, two week IG orientation course began to be taught in selected overseas areas.

1960 - 1990

In May 1956, the Secretary of the Army directed the Department of the Army to assume responsibility for technical proficiency inspections (TPI) of Army atomic organizations worldwide. General Order #40, dated 24 August 1956, placed these inspections under the jurisdiction of the IG. The March 1960 revised AR 20-1 for the first time provided policy concerning IG technical proficiency inspections.

IG Technical Bulletin #4, published in 1960, for the first time standardized the approved method and procedures for IGs to receive and process Inspector General Action Requests (IGAR). In 1962, an OTIG investigation looked into allegations of inefficiencies during the call up of Reserve and National Guard units during the Berlin buildup.

The US Army IG philosophy began to be shared with out allies when the OTIG presented its standard course of instruction to groups composed entirely of foreign officers. In FY 61, instruction was presented to Republic of Korea Army officers in Seoul, Korea, and to Nationalist Chinese Army Officers in Taipei, Formosa.

The early 1980s heralded a significant change in the way IGs did inspections. Traditionally, general inspections had focused primarily on evaluating a unit's compliance to regulations. However, purely compliance inspections tended to address symptoms rather than causes and made the assumption that policy guidance and directives were correct.

The new emphasis for IGs was on a compliance-systemic inspection methodology. This focused attention on causes rather than symptoms. allowed policy errors or omissions to be addressed for resolution, traced unit problems to Army problems, emphasized correction at the proper level, and minimized the need for onetime unit inspection preparation. Follow-up inspections were also stressed, primarily to verify that corrective action was carried out and to ensure the corrections truly solved the problems.

In 1986 Goldwater-Nichols Reorganization Act reversed the IG portion of the 1950 Army Reorganization Act in that now TIG became responsible to the Secretary of the Army and responsive to the Chief of Staff, Army. TIG's other responsibilities remained the same.

Also during the 1980's, the IG system became automated. Automation gave IGs the tool to better assimilate all available IG information, as well as audit reports written by outside agencies (e.g., Defense Audit Service, General Accounting Office (GAO). The first effort was called the Inspector General Management Information Resource System (IGARS). IGMIRS was later replaced by the Inspector General Worldwide Network (IGNET).
