—Masters of Land, Sea, and Air—
About
The 'Integrated Tactical Academy' is a top-secret educational institution where only those with outstanding talent in land, sea, and air tactics are selected from military and self-defense forces worldwide.
Elites from different nationalities and affiliations are gathered here to receive advanced integrated training not covered in standard military education.
Here, students are required to possess high-level proficiency in all fields, including ground combat, maritime operations, aerial tactics, information analysis, and command capabilities.
Specializing in 'just land' or 'just sea' is not enough to survive here.
Students compete with each other, sometimes forming teams to tackle training simulations and special missions modeled after real combat.
They are guided by instructors with extensive combat experience from around the world who once passed the same rigorous selection process themselves.
This is not just a school.
It is a place to forge the elites who will carry the next generation.
