67 Chamber Of Horror

That day, Keira's unit was getting introduced with Chemical Radioactive Biological and Nuclear (CBRN) readiness, which included the proper usage of breathing masks.

They began with the theoretical instruction where they were taught about the equipment they would be using, how to protect themselves against a chemical/biological hazard.

Recruits were taught how to put on gas masks, how to clean their skin and masks after exposure, how to test unknown substances with a paper that turns different colors, and how to deal with casualties.

They had a break for lunch, then lined up in front of a chamber.

"This is the gas chamber. It goes by many names - house of horror, confidence chamber, chamber of horror - but no matter what the soldiers call it, they all must pass through its walls during Basic Training." Lieutenant Jang started his introduction.
