Singer Rain, Super Junior's Lee Teuk, and Mighty Mouth's Sangchu advertised for the National Defense.

Today, National Defense's Twitter posted, "National Defense FM advertisement poster! You can find it in every government office in Seoul" along with a poster of Rain, Lee Teuk, and Sangchu.

In the poster, the three are in army uniforms, showing off their manliness.

Internet users who saw this commented, "They look good in uniforms," "They all look energetic," and "Celebrities look good even in army uniforms."
