C.T.T - closed, transferred, and transferring ranges
Caliber - The diameter of a projectile or the diameter of the bore of a gun or launching tube. Caliber is usually expressed in millimeters or inches. In some instances (primarily with naval ordnance), caliber is also used as a measure of the length of a weapon’s barrel.For example, the term “5 inch 38 caliber” describes a munition used in a 5-inch gun with a barrel length that is 38 times the diameter of the bore.
Casing - The manufactured portion of a munition that is built to hold an explosive charge and the mechanism required to fire this charge.
Chain of Custody - The activities and procedures taken throughout the inspection, re-inspection and documentation to maintain positive control of MPPEH to ensure the veracity of the process used to determine the status of material as to its explosive hazard. This includes all such activities from the time of collection through final disposition.
Chemical Agent (CA) - A chemical compound that produces lethal or other damaging effects on human beings and is intended for use in military operations.

Construction Support - Assistance provided by DoD EOD or UXO-qualified personnel and/or by personnel trained and qualified for operations involving CA during intrusive construction activities on property known or suspected to contain UXO, other munitions that may have experienced abnormal environments (e.g., DMM), munitions constituents in high enough concentrations to pose an explosive hazard, or CA to ensure the safety of personnel or resources from any potential explosive or CA hazards.
Cultural Debris - Materials found on operational ranges or munitions response sites that are not related to munitions or range operations. These may include, but are not limited to: rebar, household items (refrigerators, washing machines, etc.), automobile parts and automobiles that were not associated with range targets, fence posts, fence wire, and magnetic rocks.

Detonation - A violent chemical reaction within a chemical compound or mechanical mixture evolving heat and pressure. The result of the chemical reaction is exertion of extremely high pressure on the surrounding medium, forming a propagating shock wave that originally is of supersonic velocity. A detonation, when the material is located on or near the ground surface, is normally characterized by a crater.
Discarded Military Munitions (DMM) - Military munitions that have been abandoned without proper disposal or removed from storage in a military magazine or other storage area for the purpose of disposal. The term does not include unexploded ordnance, military munitions that are being held for future use or planned disposal, or military munitions that have been properly disposed of consistent with applicable environmental laws and regulations. (10 U.S.C. 2710(e)(2))

This documentation must be signed by a technically qualified individual with direct knowledge of: (1) the results of both the material’s 100 percent inspection and 100 percent re-inspection or of the approved process used and the appropriate level of re-inspection, and (2) the veracity of the chain-of-custody for the material. This signature is followed by the signature of another technically qualified individual who inspects the material on a sampling basis (sampling procedures are determined by DoD entity that is inspecting the material).
