Well, the simplest way of putting it is a Tamer's task force. Basically protecting both tamers and digimon from the various threats in this world, no matter what form they take. There are currently 2 branches; one at the Royal Base and one in Neon City. There are also both Primary and Secondary agents. Primary agents, such as myself, are put into units and tasked as such. Secondary agents are called upon whenever needed, however they are not a part of a specific unit.

A good assessment of it would be the Digital Worlds version of the Power Rangers, only without the cheap effects.
