Why Carpe Noctem?
Soldiers know the night. It gave us cover, stealth, and an advantage, and some of the most important missions are done after dark. It's also where the hardest fights happen: the ones in the mind, when no one is watching.
That's why this year's theme is Carpe Noctem: Seize the Night.
Many Army helicopters that carried soldiers into combat and brought them home bear Native American names or tribes: Black Hawk, Chinook, Apache, Kiowa. The Army no longer requires those names, but it kept the tradition out of respect for the people and histories behind them.
For our founder, that tradition is personal. He called in MEDEVACs and conducted air assaults aboard Black Hawks in Iraq, and called for close air support (CAS) and close combat attacks (CCAs) from Apaches and Kiowas in combat mostly during night operations. Those aircraft carried the wounded, carried soldiers to their objectives, and brought fire when it was needed.
Behind those names is a long history of Native American military service and warrior tradition. This year, Operation SISU recognizes the courage, perseverance, and service of Native American warriors and the generations of Native Americans who have served in the U.S. military.
Carpe Noctem means more than moving through the dark. It means the willingness to enter it, to keep moving when the path isn't clear, and to endure, adapt, and overcome.
That is SISU.
Sisu (Finnish): strength when the tank is empty, courage when the odds say quit, and a refusal to back down.
Register now. Seize the night.
About the artwork:
This year's design pairs a skull with a Plains-style Wíyaka wapȟáha. We chose it to honor the service of Native American warriors and to say something about the cost of war that veterans carry home.
In many Plains nations, the war bonnet is a sacred symbol, earned through repeated courage and service to the people. Native Americans have served in the U.S. military for generations, at some of the highest rates of any group. Many carried what every veteran carries: courage in combat, then a private fight afterward that no one saw. The skull stands for the warrior whose struggle was invisible, and for the reminder that no one is immune, including those who lead and carry the most for others.
