In many U.S. states, marshals can be found acting at the state, local or municipal level; marshals can be court bailiffs or process servers, or even fully sworn police officers. In some states, they may be sworn peace officers, however their job is, in certain cases, entirely civil rather than criminal law enforcement. In other states, some communities maintain a Town or City Marshal who is responsible for all general law enforcement within the respective jurisdiction, as well as court duties, while others are strictly court officers. This is especially true in communities with both police and marshals. The position of Marshal vastly differs from state to state. At least one local railroad servicing company's part-time public safety staff, which are both fire and police trained, is supervised by a chief marshal.
