Since 1846, the 3d Cavalry Regiment has served the United States through war and peace to protect and secure the country's frontier, secure its growth as a world power, and defeat the forces that have threatened our country's very survival. Most recently, the Regiment has served with distinction in combat operations in Iraq.

The 3d Cavalry Association was formed in 1995 to preserve the history, traditions, and heritage of this storied Cavalry Regiment. The Association's special charter is to support the veterans, troopers, and family members of the Regiment. Most recently, the Association has formed the General James H. Polk Scholarship fund to provide for the education of the children of our fallen troopers. The 3d Cavalry Association is recognized as Tax exempt by the Internal Revenue Service under Section 501 (c) (3).
