NBC suit
An NBC (nuclear, biological, chemical) suit, also called a chemsuit or chem suit or chemical suit is a type of military personal protective equipment. NBC suits are designed to provide protection against direct contact with and contamination by radioactive, biological or chemical substances, and provides protection from contamination with radioactive materials and some types of radiation, depending on the design. It is generally designed to be worn for extended periods to allow the wearer to fight (or generally function) while under threat of or under actual nuclear, biological, or chemical attack. The civilian equivalent is the Hazmat suit. The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.
Logo of NBC
Contrary to popular belief, the Peacock was not originally used as NBC's official primary logo; the 1956 and 1962 versions were used solely to identify the network's color broadcasts, while other logos, initially the xylophone logo but most commonly the NBC snake logo, identified NBC itself. The Peacock became so identified with NBC that it was incorporated into the network logo in 1979 by Fred Silverman, then President of NBC, due to prior research from 1977 in NBC's corporate planning department by Peter H. Kliegman who recommended the station identification value of the Peacock and suggested the Peacock be utilized as a logo. The Peacock became the sole logo in 1986.
