CHARLIE SHEEN is donating one-percent of the profits from his FX show "Anger Management" to the USO.
--He's guaranteeing the donation will be at least $1 MILLION, but there's no limit on how high it can go.
--Charlie will hand over the first installment of $250,000 in a private ceremony later this week.
--He says, quote, "It's an honor for me to be able to give back to these men and women of the military who have done so much for all of us.
--"They put their lives on the line for us every day, and I'm just happy that my work on 'Anger Management' can bring a little bit of relief to the troops and their families."
