Joint Expeditionary Force requires credible deployable capabilities for effective grey zone threat combat.
Conclusion
The Joint Expeditionary Force’s freedom to operate independently should allow it to be more responsive and agile in combatting grey zone threats. But it can only do this if it possesses credible, deployable capabilities. Expanding membership of the JEF might also bring benefits. (Conclusion, Paragraph 44)
