&quot;Delta Force&quot; is not what it&#x27;s called, either.  The Army cycles through bureaucratic sounding names -- &quot;Combat Applications Group&quot; for example -- in order to keep it confusing.  &quot;Delta&quot; comes from one of these names -- &quot;Operational Detachment: Delta.&quot;  This sounds like an unimportant support team for a Special Forces group.  &quot;OD: Alpha&quot; is the main team of green berets (aka, &quot;ODA&quot; or &quot;the A-Team&quot;).  They are supported by &#x27;OD: Bravo&quot; and &quot;OD: Charlie&quot; (logistics support, etc.).  So &quot;OD: Delta&quot; sounded meaningless to an uninformed listener.  By the time Chuck Norris made &quot;Delta Force&quot; a known name for the pinnacle of Army Special Ops, they weren&#x27;t actually called that anymore in reality.
