The Tri-Service Brigade: Cornell's Joint ROTC Community

Cornell's Army, Naval, and Air Force ROTC programs share Barton Hall and a calendar of joint traditions — memorial physical training, the annual Watchfire, and the Tri-Service Military Ball.

One building, three programs

Barton Hall houses Cornell's Army, Naval, and Air Force ROTC programs, and the three train side by side — sharing the drill deck, joint organizations like the Joint Service Color Guard and Scabbard and Blade, and the annual traditions below, which cadets describe as Tri-Service Brigade events.

The annual Watchfire

Each year Detachment 520 cadets join the Watchfire held with Vietnam Veterans of America New York Chapter 377. Retired American flags are honorably placed on the pyre, the fire is lit at dusk, and cadets stand watch through the night — a tradition of remembrance shared with the veteran community.

The photographs on this page show the detachment's participation; they do not imply Chapter 377's endorsement of this website.

The Tri-Service Military Ball

The year's most formal tradition brings all three programs together: an annual military ball hosted by the Tri-Service Brigade, with a distinguished guest speaker each year, the posting of the colors, toasts, and an evening that belongs to the whole Cornell ROTC community.
