FM 6-50, MCWP 3-1.6.23 CANCEL
CATV a command which, when coupled with an order, rescinds that order. For example, CANCEL CHECK FIRING indicates the previous order to check firing is no longer in
effect. CEASE LOADING a command that prohibits a section from loading another round. CECOM Communications-Electronic Command CEP circular error probable CF command/fire (radio net) CFB chief of firing battery CFST critical fire support task chan channel charge the propellant of semifixed or separate-loading ammunition. CHECK FIRING a command given to cause an immediate halt in firing. chg charge close-in aiming point an aiming point set up in the
cmd comm platoon area. The primary close-in aiming point is the infinity collimator, a lightweight optical instrument that simulates an aiming point at infinity. A secondary close-in aiming point is a set of two aiming posts. When aligned, the two posts establish a line along which the panoramic telescope is sighted when
laying for direction. an infinity reference device used as a
close-in aiming point during indirect fire. common deflection the deflection corresponding to the azimuth of fire that the FDC has input into the BCS and BUCS. The common deflection for all weapons with an M100-series sight is 3200. For the M101A1 it is 2800. common grid the extension of survey control (direction, location, and altitude) from a base datum to all fire support assets requiring orientation and positioning data within a com- mand. Note that the USMC terminology is common survey. complete rounds term that includes the various components of a round required to perform the firing function. There are four components in a complete round: a primer, a propellant, a projectile, and a fuze. comp site complementary angle of site COMSEC communications security continuous fire fires delivered by loading and firing as rapidly as possible consistent with accuracy and within the prescribed rates of fire for the pieces. cookoff functioning of chambered ammunition caused by the heat of the weapon rather than by normal firing. coppering metal fouling left in the bore of a cannon by the rotating band of a projectile. corr correction counterfire fires directed against indirect-fire systems, to include their weapons, command and con- trol, communications, ammunition, and target acquisition components. counterrecoil forward motion of a cannon returning to firing (in-battery) position after recoil. CP command post or concrete piercing (fuze) Cphd Copperhead crater analysis process by which the direction to an artillery or mortar unit is determined from analysis of the shell crater. Additionally, shell fragments are collected to determine the type of shell that caused the crater. crest a terrain feature of such altitude that it limits the minimum elevation of a weapon. crew-served weapons weapons, such as machine guns or howitzers, that require two or more persons to operate.
