JACKSONVILLE, Florida (CNN) - President Barack Obama said Monday that the 14 Americans killed in two helicopter crashes in Afghanistan "were doing this nation proud."
He said they "gave their lives ... to protect ours."
Ten Americans were killed in one incident and four were killed in another, according to NATO's International Security Assistance Force.
"Now, it is our duty, as a nation, to keep their memory alive in our hearts and to carry on their work, to take care of their families, to keep our country safe," Obama said, speaking at the Naval Air Station in Jacksonville.
