Enforcement provides the specialized peace-keeping talent for the ISB, occasionally for Internal Affairs, but most often they lend their expertise to Investigations. Gathering the more covert operations experts within the branch of Enforcement, coupled with the ability to call upon the strong arm tactics of the standard Imperial Military, the ISB has sufficient brawn and firepower to back its intricate information and intelligence agencies.

Usually unlike the other branches of the ISB, enforcement concerns itself with specialized, and often independent, operatives contracted to achieve ends endorsed by the ISB. These contracted operatives are put to use by many of the different departments, but there is some tension caused by those employed who are not COMPNOR members.

Enforcement employs or contracts individuals and/or organizations such as freelance enforcement specialists, contract-specific peace officers, contracted data-slicing agents, and independent combat experts.
