Def Con One 

Def Con One is a heavy metal band, that contains 4 members. They're not the most popular of all bands, but they hold good music, and they are very talented. The lead singer sings at home, and made his girlfriend a song for valentines day, witch is one of the best songs i've ever heard, but he has not made it into an official single, witch his kids are hoping he one day will do. They are all great members and the bands music is really great. 10/10 for effort.

Adrian:Have you heard of Def Con One?

Adrian:Yes, their music is great and the members are very nice and genorous.
Stephan:I know, i would love to meet them, their family must be so proud.

Defcon 1 

A defense readiness condition (DEFCON) is an alert posture used by the United States armed forces. The DEFCON system was developed by the Joint Chiefs of Staff and unified and specified combatant commands. It prescribes five graduated levels of readiness (or statuses of alert) for the U.S. military, and increase in severity from DEFCON 5 (least severe) to DEFCON 1 (most severe) to match varying military situations.

DEFCONS are a subsystem of a series of Alert Conditions, or LERTCONs, that also includes Emergency Conditions (EMERGCONs).3 DEFCONs should not be confused with similar systems used by the U.S. military, such as Force Protection Conditions (FPCONS) and Watch Conditions (WATCHCONS), or the Homeland Security Advisory System used by the United States Department of Homeland Security. The highest confirmed DEFCON ever was Level 2 (DEFCON2). Movies and popular culture often misuse the DEFCON system by "going to DEFCON 5" during a state of emergency. In fact, DEFCON 5 is the lowest state of readiness. DEFCON 1 is the most severe.
