Fire support coordination element Fire support coordination element A fire support coordination element (FSCE) is a term used in the US Army to identify an element of military formation or unit organisation in which functions are directly related to positioning weapons and delivering their fire onto targets. The term is most often associated with artillery, but is sometimes used for mortar fire. During the Vietnam War, the element, which included about five officers and nine enlisted personnel, collected and assessed information provided by the forward observers, field unit liaison officers, AN/TPS-25 surveillance radar section, division artillery air section, visual airborne target locator section, and
Calculated Ignition Index and CCAI are calculated from the density and kinematic viscosity of the fuel. Formula for CII: Where: D = density at 15°C (kg/m³) V = viscosity (cST) T = viscosity temperature (°C) CII was designed to give out numbers in the same order as the cetane index for distillate fuels. Calculated Ignition Index The Calculated Ignition Index (CII) is an index of the ignition quality of residual fuel oil. The running of all internal combustion engines is dependent on the ignition quality of the fuel. For spark-ignition engines the fuel has an octane rating. For diesel engines it depends on
