Hours after a personal encounter with the grim cost of war, President Barack Obama said Thursday the sight of 18 flag-covered cases holding the remains of Americans killed this week in Afghanistan can't help but influence his thinking about sending more troops overseas.

"It was a sobering reminder of the extraordinary sacrifices that our young men and women in uniform are engaging in every single day, not only our troops but their families as well," Obama said from the White House, reflecting briefly on his surprise middle-of-the-night trip to Dover Air Force Base to observe the return of the fallen Americans to the United States.

Speaking softly and somewhat haltingly, Obama said losses such as these are "something that I think about each and every day."

Asked whether the somber experience _ watching cases carrying the remains come off a giant C-17 cargo plane one by one in the darkness and meeting privately with families so fresh in their grief _ will affect his overhaul of the U.S. strategy in Afghanistan, the president didn't hesitate to say that it would. But neither did he elaborate.

"The burden that both our troops and their families bear in any wartime situation is going to bear on how I see these conflicts," he said, adding nothing more.

By many accounts, it was a difficult night.

After a 40-minute helicopter ride around midnight to the Delaware base where U.S. forces killed overseas come home, Obama went immediately to a chapel to speak with relatives of the fallen. Their loved ones had died just two or three days before.

Of the 18 fallen Americans on the C-17, 10 of them _ including three Drug Enforcement Administration agents _ were killed Monday when a U.S. military helicopter crashed returning from a firefight with suspected Taliban drug traffickers in western Afghanistan. The other eight soldiers were killed Tuesday when their personnel vehicles were struck by roadside bombs in Afghanistan's Kandahar province.

The military calls the process of removing remains from the plane a dignified transfer, not a ceremony, because there is nothing to celebrate. The cases are not labeled coffins, although they come off looking that way, enveloped in flags.

A group of dignitaries, in this case including Obama, boards the plane for prayers, then stands in a line of honor outside. The family is brought up in a van. Then six soldiers in camouflage and black berets carry each case down the ramp and into a waiting van.

Most of what Obama saw, though, was private.

An 18-year ban on coverage of Dover homecomings, dating to the 1991 Gulf War and strengthened by former President George W. Bush, was relaxed this year under Obama's watch. Now, families get to decide whether cameras can document the return. Nearly two-thirds have said yes to the media and even more to coverage by Pentagon cameras.

In this case, the return of only one of the 18 was open to the media.

His name was Dale R. Griffin, an Army sergeant from Terre Haute, Ind., and a top wrestler in high school and in college at Virginia Military Institute. He was remembered Thursday by friends and a former coach as particularly tenacious. Vigo County, Ind., Judge Chris Newton, a family friend, described him as "unbelievably tough and resilient."

It is unclear why the other families declined coverage.

But none who came to Dover was told that Obama was coming until they were already there, so his planned presence was not a factor, said Dover spokesman Air Force Maj. Carl Grusnick.

The wife of Army Pfc. Brian Bates, who died Tuesday in Afghanistan, said she changed her mind and decided against allowing coverage after learning by phone around 11 p.m. EDT Wednesday that Obama would attend.

"Brian met the president, and that's all that matters," Enjolie Bates, who was not at Dover for the transfer, said in a telephone interview from her home in Lakewood, Wash. "I know he would like that. We didn't need to broadcast it to the world."

Both Marine Col. David Lapan, the Pentagon's public affairs director, and White House press secretary Robert Gibbs said there was no suggestion from the government for the families to lean either way on media coverage. Continued...
