EPEX has dropped a dance practice video for "Full Metal Jacket."

The dance practice video features the C9 Entertainment boy group going over their choreography in an agency practice room. "Full Metal Jacket" is the lead single on the group's 6th mini album 'Prelude of Anxiety Chapter 2. Can We Surrender?,' and the song is about being surrounded by enemies and breaking out anyway.
