The Texas Military Department also maintains a variety of civic engagement initiatives to support public relations, accountability, transparency, and safety awareness.

"[8] It is empowered by Article 4, Section 7 of the Texas Constitution to "execute the laws of the State, to suppress insurrections, and to repel invasions.

In the years between the Texas Revolution and Mexican War as a sovereign republic, the department remained active in land, sea, and guerilla combat operations and expeditions.

They are credited with leaving Texas the only Confederate state unconquered by the Union Army following three failed efforts, including the Second Battle of Sabine Pass, which is also among the most notable victories of the Civil War.

[9] The Texas Military Department is required by law to maintain duplicate federal and state offices for many administrative functions such as human resources, finance, and payroll.

TMD divides these traditional agency functions between federal administrative offices under the adjutant general's chief of staff and a state executive director.

OAG is the principal staff element of the Adjutant General in the exercise of policy development, planning, resource management, fiscal and program evaluation and oversight, and interface and exchange with other Texas Government departments and agencies, foreign governments, and international organizations, through formal and informal processes.

Despite the implications of the title, the executive director reports to the adjutant general, who ultimately maintains responsibility for all department activities and decisions.

Overall, the executive director generally functions as the voice for state administrative concerns within the department's larger military organization.

The joint staff coordinates operations using the Texas Military Forces and advises on common functions such as readiness, planning, and logistics.

The Domestic Operations Command, commonly referred to as DOMOPS, is a unified command of the Texas Military Department established in 2011 to improve response time, maximize equipment and personnel capabilities, place various critical domestic operations programs on a sustainable footing, and maximize use of public taxes for the Texas Military Forces.

They include infantry, paratroopers, special forces, armored cavalry, field artillery, communication, cyber, intelligence, support, medical, engineering, civil affairs, and weapon of mass destruction response units totalling over 23,000 service members.

The Texas Military Department developed and maintains an eponymous software application for smartphone operating systems iOS,[20] Android,[21] and Windows.

It enables citizens to learn about TMD's missions and capabilities and interact with Texas Military Forces service members.

The event includes helicopter demonstrations, emergency and first responder displays, World War II reenactments, children's activities, and a career fair.

[29] It provides 5th grade students with free instruction in science, technology, engineering, and math (STEM), in addition to aviation and aerospace.

The curriculum consists of rigorous activities, interactive investigations, experiments, simulations, and on-site tours demonstrating use of STEM in the workplace.

Students explore STEM careers, processes for goal setting and teamwork skills, the importance of staying in school, and remaining a life-long learner.

Certified educators teach the curriculum with the assistance of Texas Military Forces service members and community volunteers with technical and content expertise.
