(CNN) -- About 2,000 Marines and sailors will return home Friday to Camp Pendleton in California after being deployed seven months overseas.

During their deployment, the group helped deliver aid to victims of the massive floods in Pakistan and helped to fight pirates in waters near Somalia.

"From humanitarian assistance operations in Pakistan to anti-piracy operations in the Gulf of Aden, our Marines and sailors executed every mission with skill and professionalism," Col. Roy Osborn said.

The Marines and sailors will be greeted with a big celebration at the Southern California base, Osborn said.

Along with the Camp Pendleton group, thousands of other soldiers will be coming home for the holidays, said the United Service Organizations.

The USO said it will have members at airports in Atlanta, Dallas, Denver, Pensacola, Florida, and Columbia, South Carolina, welcoming thousands of soldiers home in the days before Christmas.

But the organization also will have programs in Afghanistan and Iraq for the soldiers who are not able to get home, the USO said.

"As we decorate trees, wrap presents and celebrate the holidays, let us not forget the thousands of troops deployed to Afghanistan, Iraq and other overseas locations who are left only to quietly remember the food and fellowship this holiday season brings," a statement said.
