Anons, MI is not on the list of agencies under the Hatch Act. I double checked and MI is not under any of the agencies listed either.
>The Military Intelligence Corps (sometimes referred to as MI) is the intelligence branch of the United States Army. The primary mission of military intelligence in the United States Army is to provide timely, relevant, accurate, and synchronized intelligence and electronic warfare support to tactical, operational and strategic-level commanders. The Army's intelligence components produce intelligence both for Army use and for sharing across the national intelligence community.

Comparison to Other Intelligence Community Members
CIA
DIA and the Central Intelligence Agency (CIA) are distinct organizations with different functions. DIA focuses on national level defense-military topics, while CIA is concentrated on broader, more general intelligence needs of the President and Cabinet. Additionally, due to DIA's designation as a combat support agency, it has special responsibilities in meeting intelligence requirements specifically for the Secretary of Defense, the Joint Chiefs of Staff, and Combatant Commanders, both in peace and at war. Although there are misconceptions in the media and public about the DIA–CIA rivalry, the two agencies have a mutually beneficial relationship and division of labor. According to a former senior U.S official who worked with both agencies, "the CIA doesn't want to be looking for surface-to-air missiles in Libya" while it is also tasked with evaluating the Syrian opposition.[7] CIA and DIA Operations Officers all go through the same type of clandestine training at an interagency Defense installation under CIA administration, best known in popular culture by its CIA nickname "The Farm".[7]
>DIA and the Military Services
>DIA is not a collective of all U.S. military intelligence units and the work it performs is not in lieu of that falling under intelligence components of individual services
