He also remembered Mills' lighter side. As in the night he and a confederate crept up on a Marine standing watch, tossed a dummy grenade into the post, and videotaped him as he dove for cover.

"It sounds cruel to anyone who doesn't understand," Nelson said. "That's how Marines act. … It was hilarious."

Communities across the United States remembered the nation's war dead Monday in ceremonies at cemeteries, memorials and monuments.

At Arlington National Cemetery, President Barack Obama spoke of Knutson-Cullen, a 2003 graduate of Liberty High School in Eldersburg who left Maryland for the U.S. Military Academy.

"Captain Sara Cullen had a smile that could light up a room and a love of country that led her to West Point," Obama said. "And after graduation, Sara became a Black Hawk pilot — and married a former Black Hawk pilot.

"She was just 27 years old when she and four other soldiers were killed in a helicopter crash during a training mission near Kandahar. This past April, Sara was laid to rest here, in Section 60."

Obama then named others interred at Arlington, and concluded: "Today, we remember their service. Today, just steps from where these brave Americans lie in eternal peace, we declare, as a proud and grateful nation, that their sacrifice will never be forgotten."
