A limber is a two-wheeled cart designed to support the trail of an artillery piece, or the stock of a field carriage such as a caisson or traveling forge, allowing it to be towed. The trail is the hinder end of the stock of a gun-carriage, which rests or slides on the ground when the carriage is unlimbered.

In the United States, state funerals are the official funerary rites conducted by the federal government in the nation's capital, Washington, D.C., that are offered to a sitting or former president, a president-elect, high government officials and other civilians who have rendered distinguished service to the nation. Administered by the Military District of Washington (MDW), a command unit of the Joint Force Headquarters National Capital Region, state funerals are greatly influenced by protocol, steeped in tradition, and rich in history. However, the overall planning as well as the decision to hold a state funeral, is largely determined by a president and their family.
