Department of Defense Directive 3000.07 - Irregular Warfare (IW) Dated August 28, 2014
Of note, it is DoD policy that:
a. IW is as strategically important as traditional warfare and DoD must be equally capable in both. Many of the capabilities and skills required for IW are applicable to traditional warfare, but their role in IW can be proportionally greater.
b. DoD will be proficient in IW.
c. IW is conducted independently of, or in combination with, traditional warfare.
