Which major command provides technical assistance to mishap investigation boards?

The major command that provides technical assistance to mishap investigation boards is the Air Force Materiel Command (AFMC). This command has a specialized role focused on sustaining and managing the Air Force's weapon systems and equipment. AFMC's technical expertise and resources are crucial in investigating mishaps, as they can provide insights into the design, manufacture, and maintenance of munitions and systems involved in the incidents.

By having technical personnel from AFMC involved, investigation boards can access information and analysis that may not be readily available from other commands. The critical evaluation of factors such as equipment failure, human error, or procedural issues is supported by AFMC's technical knowledge, making their contribution invaluable in determining the root causes of mishaps and enhancing safety measures in the future.
