20th Infantry Regiment
“Tant Que Je Puis”
The U.S. Army Cadet Command established the Regimental Affiliation Program in 1985 to foster unit cohesion, camaraderie, esprit de corps, and the pride of belonging among the diverse groups of Cadets attending the Leader Development and Assessment Course from states around the nation.
Cadets attending LDAC have the unique privilege of being members of one of the Army’s finest combat units. Through the Regimental Affiliation Program, each Cadet organization is assigned to an active Army regiment. The goal of the program is to bind Cadets and cadre together in a close-knit and dynamic organizational relationship with a strong sense of teamwork so crucial to success at LDAC.
LDAC’s 4th Regiment is affiliated with the U.S. Army’s 20th Infantry Regiment. “Tant Que Je Puis.”
