The 30th Armored Division carried Tennessee's armor lineage into the Cold War and took its nickname from the Volunteer State. It never went to war as a division, but it kept a heavy-force structure alive in the Guard until reorganization ended the formation in the 1970s.

The Grizzly Division was built from post-Korean War California Guard forces and represented one of the National Guard's true heavy armored formations. It trained for mobilization in a Cold War tank war and was briefly called for domestic emergency duty during the Watts riots.

The Hurricane Division began as a postwar Guard infantry formation before converting to armor in the 1950s. Florida and Georgia troops kept its heavy structure alive through the high Cold War years until the big Guard reorganization of 1968.

The Lone Star Division was one of the National Guard's longest-lived armored formations. Texas kept it on the books for decades, including a federal activation during the Berlin Crisis, and the division survived all the way into the early 2000s before finally being reorganized.

The 50th Armored Division was one of the first postwar Guard armored divisions and carried New Jersey's Jersey Blues heritage into the tank age. It remained a major reserve heavy formation through the Cold War before the post-Soviet drawdown finally ended the division.
