An impressive array of Hollywood stars have lent their support to charity organization Got Your 6 in a brand-new PSA spot.

The A-listers appearing in the clip include Mike & Molly star Melissa McCarthy (pictured above with Got Your 6 managing director Chris Marvin at the PSA taping), Academy Award nominee Jeremy Renner (pictured below), Renner's The Avengers co-stars Mark Ruffalo and Chris Evans, Jessica Chastain, Modern Family's Eric Stonestreet and Scandal's Kerry Washington.

Other celebs who support the cause are names like Kevin Bacon, Jay Leno, Conan O’Brien, Ryan Seacrest, Aerosmith's Steven Tyler, John Mayer, Minka Kelly, Brooklyn Decker, Meghan McCain, Sara Evans, Flo Rida, and Eva Longoria.

So what is Got Your 6? More after the jump.

Got Your 6 is described as "a campaign that unites the entertainment industry with expert nonprofit organizations that focus on veterans and military families." It aims to bridge the divide between military and civilian life for the more than one million servicemen and women who are expected to complete their service in the next five years.

In addition to putting together star-studded PSAs, the group offers ways for the public to help these returning veterans, whether it's direct donation or uniting them with the right organization for them to take action in a variety of ways. It can be something as big as hiring a veteran or supporting a job fair, or something as small as learning about PTSD or spreading the word about the cause.

All the important information is available at the Got Your 6 website, the address of which is viewable at the end of the new ad.
