What significant event led to the reestablishment of the MA rate?

The reestablishment of the Master-at-Arms (MA) rating in the U.S. Navy was primarily driven by societal changes and a heightened focus on discipline, security, and law enforcement within the military during a turbulent time in the nation's history. The race riots across the U.S. in the 1960s spotlighted significant social unrest and a need for military personnel who could manage internal security and uphold order effectively.

Master-at-Arms personnel are responsible for enforcing laws, regulations, and maintaining order among naval personnel, which became crucial in a context where societal tensions were high. The decision to reestablish the MA rating was a direct response to the need for structured security measures and a dedicated force that could address emerging challenges, including the need for improved policing within the Navy.

Thus, the rise of race riots highlighted an urgent need for trained individuals who could focus on law enforcement and maintain peace in a period of widespread civil disorder, making this choice the most accurate representation of the significant event that led to the MA rating's reestablishment.
