Gary Sinise may be better known for his support of the U.S. military than his acting career. And that’s saying something.

Sinise’s work in such iconic films as “Forrest Gump” and “Apollo 13,” as well as his long stint on “CSI: NY,” have made him a household name. Yet his tireless, authentic efforts on behalf of the troops, highlighted by his crowd-pleasing Lt. Dan Band appearances, have earned him the military’s respect.

He is far from the only star who donates his time, money and resources to help the men and women of the U.S. military. That support transcends ideological fences. The late Robin Williams didn’t agree with the U.S.’s invasion of Iraq, but he recommended other stars adjust their schedules as he often did to visit American troops across the globe.

Check out this list of some of the celebrities who put partisanship aside for the sake of the U.S. military.

Toby Keith
The country superstar doesn’t just support the troops in fiery fashion via songs like “Courtesy of the Red, White and Blue.” He routinely visits troops overseas, performing his country classics over the past 13 years while getting to know them on personal level. He earned the Spirit of the USO Award last year after playing for more than 250,000 military personnel.

Kathy Griffin
The D-list doyenne is known for her tabloid obsessions. She still finds time to give back, although sometimes the results aren’t what she expects. She first traveled to Afghanistan in 2003 to bring laughter to those military in harm’s way. The visit left her inspired. She later organized an annual Toys for Tots program specifically for military families. Her turn at hosting 2010’s “VH1’s Divas Support the Troops” telecast hit a snag when she lobbed a fat joke against Bristol Palin and got a chorus of boos in response.

Bruce Willis
Yippee Ki-Yay, indeed. The “Die Hard” veteran regularly gives his time and talents for the troops. Last year, he recorded a Christmas-themed message thanking the military for all they do on the U.S.’ behalf. He previously brought his rock band The Accelerators to Iraq in 2003 to perform for troops.

Charlie Sheen
Yes, Mr. Tiger Blood himself has a soft spot for the U.S. military. Three years ago he promised to donate one percent of the profits from his FX series “Anger Management” to the USO, with a minimum amount of $1 million and no cap from there.

Wayne Newton
The veteran crooner’s first time singing with the USO came at the tender age of 7. By 2001, Newton took over as chair of the USO Celebrity Circle to the delight of Dolores Hope, whose husband, Bob Hope, did the others for decades. Newton told the Los Angeles Post-Examiner earlier this year he’s only been turned down by two stars since assuming his official USO duties.
