via Oprah Winfrey and Michelle Obama have joined forces to shed light on the sacrifice military families make when their loved ones go into battle. When asked on Thursday's The Oprah Winfrey Show what impresses her most about these families, Obama said, "Their strength. Their pride. Their courage. Their willingness to sacrifice without complaint moves me every single time."

"Whenever I'm feeling bad, feeling sorry for myself, I suck it up because of these families," she added. The First Lady will be joined by journalists Tom Brokaw and Bob Woodward to honor military families who have shouldered the burden of fighting in Iraq and Afghanistan for nearly a decade.

As for why Obama is speaking up, she says it's because someone has to. "Part of the challenge of getting the message out about military families is they never ask for help," she said. "They never ask for help because you don't do that when you're in the military. You get it done. That's how you're trained. That's what you're taught."

The Oprah Winfrey Show: The Bravest Families In America With First Lady Michelle Obama, Tom Brokaw, Bob Woodward airs on Thursday January 27, 2010.
