A few years ago, the Pentagon began a blanket review of all valor awards to see if they should be upgraded.
Bellavia is being honored for his heroism on Nov. 10, 2004 when he was a squad leader in Operation Phantom Fury, an American offensive on the western Iraqi city of Fallujah an Iraqi insurgent stronghold.
The Army veteran is credited with saving his entire squad that day after being pinned down by enemy fire coming from a block of houses.
"He quickly exchanged an M16 rifle for an M249 Squad Automatic Weapon, entered the house where his squad was trapped, and engaged insurgents, providing cover fire so that he and his fellow soldiers could exit safely," said a White House statement announcing his award.
When an armored Bradley Fighting Vehicle could not fire directly into the house, Bellavia re-entered the house armed only with an M16, and attacked insurgents who had been firing rocket-propelled grenades.
"He proceeded to kill one insurgent and wound another, who then ran to another part of the house," said a White House statement announcing his award. "Then-Staff Sergeant Bellavia was soon engaged by another insurgent rushing down the stairs when the previously wounded insurgent reemerged to engage him as well." Bellavia was able to return fire and killed both attackers.
"He then took enemy fire from an insurgent who had appeared from a closet across the room. He pursued him up the stairs and killed him," said the statement.
Bellavia then to the roof "where he engaged and wounded a fifth insurgent, who fell from the roof of the building."
For his heroism, Bellavia was awarded the Silver Star, the nation's third highest award for valor; the Distinguished Service Cross is the nation's second highest. His award is being upgraded to the Medal of Honor as part of the Pentagon's three-year review of valor awards for the wars in Iraq and Afghanistan that was prompted by concerns that acts of heroism were not being appropriately honored.
David Bellavia enlisted in the United States Army in 1999 and after serving in Kosovo, he deployed to Iraq in 2004 with Company A, Task Force 2-2, 1st Infantry Division.
Since leaving the Army in August 2005 Bellavia has been active in veterans advocacy groups and philanthropic organizations.
Bellavia is also the host of a radio talk show for WBEN in Buffalo, New York.
On Monday morning, Bellavia told his listeners the news of his award was "not really registering."
"I'm going to see guys I haven't seen in 15 years. I'm going to think about them. I'm going to just think about the guys we lost the most," said Bellavia. "It just brings you right back.
"One guy gets attention, but none of that's possible without the work of, you know, 25 guys that nobody talks about," he said. "And in this fight, in this circumstance, it was just a group of guys that were out-gunned, and we -- we fought our way through it together."
"This award is our award, and they're, we all consider it something that we did together," he added.
