Infantry, Leader and Fitness Courses

The Infantry Qualification Course provides a logical progression of individual skills and tasks selected to develop disciplined and confident soldiers that are proficient in Common Skill Level One tasks and critical 11B10 Infantry Tasks. Aligns the development of competencies (knowledge, skills, abilities, attributes, and behaviors) in volunteers and enables their transformation into Army military professionals that are prepared (physically and mentally) to meet the rigors of the warrior tasks and battle drills. Graduates will be trained and educated in the skills of their military occupational specialty, enabling them to contribute as an effective team member at their first unit of assignment. Soldiers will also demonstrate proficiency in engaging targets with Individual and Crew-Served Weapons. 11B10 OSUT incorporates the Army Learning Model (ALM) which supports adaptive soldier training and education through practical exercises and enable soldiers to demonstrate mastery of individual tasks. Drill sergeants/instructors will integrate learner centricity into learning content that enable learners to understand what they are learning and why it is important.

Course Outcome:

The Infantryman will possess the ability to demonstrate proficiency and confidence to shoot, move, communicate, survive and adapt in situations required to become a productive member in their first unit of assignment.

Instructor Courses

The Instructor Course, one of two courses that comprises the Common Faculty Development Program, is a 10-day/80-hour course designed for new faculty (e.g., instructors, trainers and facilitators). It is a competency-based course: the learning objectives are based on internationally recognized instructor competencies published by the International Board of Standards for Training, Performance, and Instruction (IBSTPI). The course prepares new faculty to teach, train and facilitate learning in an adult learning environment. It introduces new faculty to Army instructor roles and responsibilities, teaching and learning models and professional and ethical requirements. The course also introduces classroom management techniques, the process for building learning objectives and lesson plans, and characteristics of effective communication. Throughout the course, new faculty will have an opportunity to practice teaching, working from short, simple practicum exercises to increasingly longer and more complex ones, culminating in an end of course lesson presentation. The first half of the course focuses on characteristics of effective instructors, self-awareness of differences in teaching and learning style preferences, and fundamentals of teaching and learning as they apply to adults. The second week focuses more on application of those fundamentals in various teaching and learning practicums, with both instructor, peer and self-assessment in a collaborative learning environment. The summative assessment will occur at the end of the course and consist of an individual 30- to 50-minute practicum.

138th Regiment Indiana Patch

The distinctive unit insignia (DUI) for the 138th Regiment symbolizes the service of the former organization, the 138th Armor Battalion. It is depicted by the golden leopard springing upon its prey, indicating the unit’s ability to move swiftly and silently while stalking its prey, then striking at the opportune moment with all the power and force at its command. It is felt that the leopard represents the animal most typical of this type of attack-powerful, silent, and swift, who by means of cunning as well as great strength is the greatest of all hunters. The eye of the leopard is emerald green, symbolic of its ability to see and hunt in the dark. Thus, the motto associated with the 138th Regiment is “Seek and Destroy.”

The lineage of the 138th Regiment can be traced back to September 1942 when it was formed as the 638th Tank Destroyer Battalion. In 1951, it was re-designated as the 138th Tank Battalion, and in June 1960 re-designated as the 138th Armor Battalion. The 138th Armor Battalion was inactivated and the colors were cased in June 1967.

The Indiana Military Academy was established in 1956 as an Officer Candidate School at Indianapolis. In December 1965, the Indiana Military Academy was moved to Camp Atterbury. After moving to Camp Atterbury, the curriculum was expanded to include Non-commissioned Officer Education Courses and Military Occupational Specialty Qualification Courses.

In 1996, the Indiana Military Academy was reorganized as part of The Army School System and given the designation as the 138th Regiment (Combat Arms). Restructured with a Headquarters and General Studies Battalion, the 138th Regiment was responsible for Combat Arms Training within a region consisting of six states: Indiana, Illinois, Ohio, Michigan, Minnesota and Wisconsin.

Today, the 138th Regiment conducts Officer Candidate School, Warrant Officer Candidate School and Combat Arms Training for Soldiers not only from Indiana but throughout the Army National Guard and Army Reserve.

COVID-19 Mitigation and Response

Fiscal Year 2023: The 138th Regional Training Institute is providing the following instructions for safe institutional operations in order to mitigate and respond to risks associated with the COVID-19 pandemic. This guidance supplements current force health protection measures and guidance established by the Indiana National Guard (INNG), Centers for Disease Control (CDC) and the Department of Defense.

Applicability: These instructions apply to all personnel of the 138th Regiment, whether temporarily assigned while attending a course or permanently assigned as institutional faculty or staff.

  1. RTI response practices provided in Enclosure 1 - Mitigation Practices identifies practices by category which are to be used as general guidelines or suggested means of mitigating risks. At a minimum, all personnel will abide by currently established CDC and DOD practices.
  2. Course managers will initiate or update risk assessments to address practices for social distancing and cleaning during transportation, housing, dining, classroom facilitation, range and/or field operations, and any other operation or mission subset that requires students, faculty or staff to be consolidated.
  3. Per CDC guidelines, the distinction made between quarantine and isolation of personnel is the identification or confirmation of a positive case. Both quarantine and isolation require the separation of personnel from others beyond social distancing practices. Additionally, personnel who have established close contact with a positive case will be quarantined and monitored.
  4. Quarantined or isolated personnel are at risk of being medically dropped for missing training hours. In an effort to ensure personnel report illness, course managers will request waivers through RTI quality assurance officer (QAO) to their respective proponents for an increase in missed hours. If no virtual learning avenues are available and the student will accrue the maximum missed hours due to quarantine or isolation, the student will be medically dropped from the course.
  5. Course managers will update their student welcome material to include an updated DD93, Unit and State point-of-contact (POC) worksheet, and the inclusion of packing list items such as masks, face coverings and hand sanitizer.
  6. Students will be screened prior to, during, and after courses using the Enclosure 2 - Service Member Screening Flowchart and Enclosure 3 - COVID-19 Screening Questionnaire.
  7. Regimental S4 will coordinate the procurement of EPA approved cleaning and disinfecting supplies and personal protective equipment (PPE).

Full-time readiness is the responsibility of each individual soldier and is not something that begins and ends with deployment. Being ready means taking proactive steps to acquire necessary skills and knowledge. It also means taking care of yourself and your family. Soldier and Family Readiness Group volunteers can help by providing avenues of support and assistance. We’re a command-sponsored organization mandated by higher headquarters. Our network includes our soldiers, those they consider family and the surrounding community.
