Valderrama went on his first USO tour earlier this year, visiting troops stationed in Germany.
"For as long as I can remember, I have wanted to go on a USO tour and visit with troops," Valderrama said in a statement. "Now every opportunity I get I go — I go to show my support, to express my thanks and, most importantly, to do whatever I can for those that protect our borders every day.
Valderrama currently voices the character Manny Garcia on Disney Channel's "Handy Manny." He co-stars with Laurence Fishburne in the upcoming "Days Of Wrath" and with Val Kilmer in "Columbus Day."
