ABSTRACT

Screening smoke minimises visibility in warfare. It is used to hide the combat weapon system, movement of personnel, etc. It is used in offensive as well as defensive operations. Hexachloroethane, white phosphorous, red phosphorous, anthracene, etc. are used in screening smoke compositions and are found to be very effective. Infrared smokes conceal the infrared emission of the target and thus reduce the effectiveness of infrared-guided missiles

This chapter provides various screening smoke compositions. It explains the Beer–Lambert law and mechanism of attenuation. It explains the absorbance and transmission, mass extinction coefficient, yield, figure of merit, factors affecting screening smoke, features of a good screening smoke, difference between white and red phosphorous, non-toxic smoke compositions and infrared attenuation. References are given at the end of the chapter.
