Who cannot demand a court martial?

The ability to demand a court martial is restricted to certain members within the military justice system. Specifically, only officers or enlisted members with specific authority can initiate this process.

When considering who cannot demand a court martial, individuals attached to or embarked on a ship do not possess the necessary authority to initiate such proceedings. This limitation is largely due to the fact that court martial demands typically require a formal chain of command and specific ranks to pursue legal action. While officers in the Navy have the authority to convene courts martial, enlisted individuals and those below a certain rank may not have the same privileges.

In contrast, officers in the Navy generally have the ability to demand a court martial, while enlisted personnel could also have a say in lesser disciplinary actions but do not hold the authority to demand a court martial process on their own. Hence, the assertion that anyone attached to or embarked on a ship cannot demand a court martial is correctly identified as the accurate response.
