The Irregular Threats

The 3 colors of TRADOC.

Irregular Threats are groups that advocate for or engage in violence to achieve ideological, religious, political, or social objectives. These organizations often operate through terrorism, insurgency, or other forms of political violence. They may target governments, civilians, or rival groups to impose their beliefs, spread fear, or destabilize societies.
