Police
Not all countries use the same words to describe these groups. In the United Kingdom, for example, patrol officers form the "uniform branch", while detectives work within the CID ("Criminal Investigation Department"). Also in the United Kingdom, not all police officers are armed, these police officers form an "Armed Response Unit" which comes under other names in different constabularies, in the Metropolitan Police Service, it falls under SFC (Specialist Firearms Command) which all MET Armed Police fall under
