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 The term NBC has been replaced by CBRN (chemical, biological, radiological, nuclear), with the addition of a new threat, radiological, meaning radiological weapon.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
NBC updated its logo once again in 2008, with all network promos and IDs ending with the peacock feathers blooming out of the peacock's body, forming the logo. The feathers also flashed in tune to the NBC chimes, which were sometimes played using different instruments other than the standard xylophone, or other sounds set to the tune of the chimes (such as a telephone for promos for "The Office", or the ringing of a cash register in promos for "Deal or No Deal"). Two versions of the 2008 logo animation were used: a 3D glass version that was used in most promos, and an occasionally used 2D logo that was also used as a generic ID. The ".com" suffix added to create the URL for promoting the network's website was sometimes featured beside the logo.
