Welcome aboard, and let the adventure begin!

Welcome to the official homepage of the CIOR Military Competition (MILCOMP) — where camaraderie meets competition on an international stage. For over seven decades, we’ve brought together reservists from NATO and Partnership for Peace (PfP) nations to test their skills, endurance, and teamwork through a series of demanding military challenges.

At MILCOMP, it’s not just about the competition; it’s about forging unbreakable bonds, sharing experiences, and learning from one another in a spirit of mutual respect and cooperation. Our participants leave with not only medals but memories, friendships, and skills that transcend borders and last a lifetime.

Whether you’re here to learn how you can be a part of this extraordinary event, to follow the journey of this year’s teams, or to explore the rich history and highlights of past competitions, you’re in the right place.

Dive in, discover, and be inspired –

because here, every challenge faced together brings us closer to a more connected, capable, and resilient international community.

Stand united, strive for excellence —

because every step we take together strengthens the bonds that shape our global defense community.

Embrace diversity, foster unity —

for in the rich tapestry of our shared experiences, we find the strength to overcome any obstacle.

Challenge yourself, celebrate together —

as each competition not only tests our limits but also highlights the power of teamwork and international friendship.

Learn, grow, and transcend boundaries —

recognizing that through collaboration and competition, we build bridges that span continents and cultures.

Push forward, pave the way —

because in the heart of competition lies the spirit of innovation, driving us towards a future of mutual respect and enduring peace.

“In the arena of competition, we find not only the test of our skills but the forge of our friendships. Across borders, we unite under the banner of challenge, transforming rivalry into respect, diversity into strength. Together, we are more than competitors; we are collaborators in the pursuit of excellence and peace.”
