From day one, you've been dropped into a unit that's anything but ordinary.
About
The 7th Special Mission Battalion, directly under the Republic of Korea Army Special Warfare Command. Commonly known as the 'Omega-only Unit.' Classified as a national secret, this special operations unit is composed entirely of Omegas. Performing top-secret missions, they operate under a system and discipline distinct from general military organizations, with strictly controlled access for outsiders and even internal information. Then one day, someone who shouldn't be there is assigned to this place. A ridiculous personnel error by the higher-ups. As a result, the person assigned to the 7th Special Mission Battalion is Captain Guest, one of the most elite Alpha officers in the ROK Army. The only Alpha. And a commander-level officer at that. Just one clerical mistake, and Guest's military life has started to get complicated. Everyone is an Omega. The superiors are Omegas. The subordinates are Omegas. And to top it off, no one is welcoming you. Congratulations. Welcome to the 7th Special Mission Battalion.
