WASHINGTON (AP) -- The U.S. military is determined to position small, quick reaction forces closer to global crises after the rapid assault on the U.S. diplomatic mission in Libya last September kept U.S. armed forces from responding in time to save four Americans.
Defense Secretary Leon Panetta and Army Gen. Martin Dempsey, the chairman of the Joint Chiefs of Staff, told Congress on Thursday that they moved quickly to deploy commando teams from Spain and Central Europe last Sept. 11, the chaotic day of the assault on the U.S. installation in Benghazi, but the first military unit didn't arrive until 15 hours after the first of two attacks.
"Time, distance, the lack of an adequate warning, events that moved very quickly on the ground prevented a more immediate response," Panetta said in likely his last Capitol Hill appearance before stepping down as Pentagon chief.
Republicans have accused the Obama administration of an election-year cover-up of a terrorist attack in the nearly five months since the assault, and they kept up the politically charged onslaught on Thursday. The military also found itself under attack, with at least one senator accusing the Joint Chiefs chairman of peddling falsehoods.
Faced with repeated questions about where units were during the attack and what they were doing, Dempsey said the military is taking steps to deal with the next crisis.
"We've asked each of the services to examine their capability to build additional reaction-like forces, small, rapidly deployable forces," Dempsey said. "A small MAGTF for the Marine Corps, for example, a Marine air-ground task force. And the Army is looking at some options as well to increase the number of these resources across the globe, where the limiting factor, though will always be basing."
Sen. Angus King, I-Maine, put it in layman's terms: "So you are moving the fire stations nearer the ...?"
"We're trying to build more firemen. The question is whether I can build the stations to house them," Dempsey answered.
In more than four hours of testimony, Panetta and Dempsey described a military faced with not a single attack over several hours, but two separate assaults six hours apart; little real-time intelligence data and units too far away to mobilize quickly. Ambassador Chris Stevens and three other Americans were killed in the attacks.
Between midnight and 2 a.m. on the night of the attack, Panetta issued orders, telling two Marine anti-terrorism teams based in Rota, Spain, to prepare to deploy to Libya, and he ordered a team of special operations forces in Central Europe and another team of special operations forces in the U.S. to prepare to deploy to a staging base in Europe.
The first of those U.S. military units did not actually arrive in the region until well after the attack was over and Americans had been flown out of the country. Just before 8 p.m., the special operations team landed at Sigonella Naval Air Station in Sicily. An hour later, the Marine team landed in Tripoli.
Defense officials have repeatedly said that even if the military had been able to get units there a bit faster, there was no way they could have gotten there in time to make any difference in the deaths of the four Americans.
"The United States military is not and should not be a global 911 service capable of arriving on the scene within minutes to every possible contingency around the world," Panetta told the Senate Armed Services Committee.
That failed to placate Republicans on the panel. In one fierce exchange, Sen. John McCain, R-Ariz., called Dempsey's statement "one of the more bizarre" and argued that if the administration had taken security threats seriously, aircraft and other military could have been located at Souda Bay, Crete.
"For you to testify before this committee that ... consistent with available threat estimates is simply false; that our military was appropriately responsive," McCain said. "What would have been an inappropriate response since ... no forces arrived there until well after these murders took place?"
The general said the military was concerned with multiple threats worldwide and, based on time and positioning of forces, "we wouldn't have gotten there in time."
Several committee Republicans pressed Panetta and Dempsey about their discussions with President Barack Obama on that fateful day and his level of involvement, suggesting that after the initial conversation the commander in chief was disengaged as Americans died.
Panetta said he and Dempsey were meeting with Obama when they first learned of the Libya assault. He said the president told them to deploy forces as quickly as possible.
