An Urgent Universal Need Statement (UUN) is defined by the Defense Science Board as "an exceptional request from a Marine Corps component commander for an additional warfighting capability critically needed by operating forces conducting combat contingency operations. Failure to deliver the capability requested is likely to result in the inability of units to accomplish their missions or increases the probability of casualties and loss of life. An UUNS may be originated only by units that are deployed to or awaiting imminent deployment to combat or contingency operations."[1]
