(CNN) -- Defense Secretary Leon Panetta provided a stark warning on Wednesday about the effects of impending budget cuts on the military unless Congress acts to avert them.
The result, he said, would be "the most serious readiness crisis" faced by the armed services in over a decade.
The outgoing secretary's address at Georgetown University included the first details of how the Pentagon would deal with the automatic spending cuts -- or sequestration in congressional jargon -- set to trigger March 1 across federal agencies.
