The Forty-Ninth Infantry Division was a unit of the United States Army, established during World War II. It was primarily composed of National Guard troops from several states, including Texas, Oklahoma, and New Mexico. The division played a significant role in various campaigns, contributing to the Allied efforts in Europe. After the war, the division was reactivated and served in various capacities during the Cold War. It was eventually inactivated in 1968, but its legacy continues through the units that have since emerged from its ranks, reflecting the ongoing commitment of the National Guard to national defense.
