U.S. military members salute at a mass re-enlistment ceremony Friday in Baghdad, Iraq.

Baqouba, Iraq ? It’s Staff Sgt. Edgar Covarrubias’ second Fourth of July in Iraq. No family barbecue, no fireworks, but Covarrubias says he’ll call his mom, wife and kids to share the day anyway.

Across Iraq, America’s Independence Day was a normal work day for most U.S. troops. But the military threw in a taste of home at larger bases with ribs, corn on the cob and red, white and blue cake.

The holiday is even leaner at smaller outposts closer to the violence, where it comes with a can of meat, some cookies and a job not yet done.

“We are not going to stop our operations to celebrate the Fourth of July,” said Sgt. Mark Johnson, 26, at a small joint U.S.-Iraqi outpost in Iskandariyah, some 30 miles south of Baghdad.

“Nothing special is planned for today and that’s OK because we didn’t expect anything,” added the 3rd Infantry Division soldier from Waterport, N.Y.

For others, the day was a reminder of their duty to their country.

At Camp Victory outside Baghdad, 1,215 troops from the Army, Marines and other services re-enlisted in a mass swearing-in ceremony led by top U.S. war commander Gen. David Petraeus. At least two husband-and-wife couples were among those signing up for another stint.

Before an immense American flag, the troops saluted Petraeus, then sang “God Bless America.”

Back at Warhorse, Sgt. Jacob Fultz, 22, of Gardner, Kan., was focused on the day’s meaning.

“It’s kind of like the fight’s never over,” said Sgt. Jacob Fultz, 22, from Gardner, Kan. “It started on July 4, 1776, and now it’s 2008.”
