UPDATE, 7:20 PM:
The U.S. casualties have dropped to 30, reports the New York Times; overall, 38 died.
Though there has been no official list of the dead, families have started to reveal their losses.
The Des Moines Register cited the loss of Jon Tumilson of Rockford, Iowa, and the Shreveport Times noted the deaths of Chief Petty Officer Robert James Reeves and Lt. Commander Jonas Kelsall. Kelsall's father confirmed he trained in San Diego.
The Army Times offers further detail, saying 17 of the special forces members who were killed were SEALs—two from the West Coast—and five were support personnel. Other military members killed were from the Army and Air Force.
The Los Angeles Times reports many of the SEAL casualties were from SEAL Team 6, the unit that took out Osama bin Laden, but those killed were NOT members who were part of the May bin Laden raid.
News continues to come in about Saturday's helicopter crash in Afghanistan, the deadliest incident in the 10-year conflict.
President Obama, in a statement on the White House Twitter feed, said, “At this difficult hour, all Americans are united in support of our men and women in uniform.”
The identities of the dead have yet to be released, pending notification of families.
