Final answer:
The review of awards for heroism varies by entity, with military awards reviewed by a military board, while civilian awards may be reviewed by local governments or organizations.
Step-by-step explanation:
The board that reviews all awards for heroism typically depends on the institution or organization bestowing the honor. For military awards, such as the Medal of Honor in the United States, this would usually be a military awards board or similar entity within the Department of Defense. In civilian cases, a local governmental body or non-profit organization might have its own review committee. The process generally involves a thorough review of the circumstances surrounding the act of heroism and validation of the facts before an award is granted.
