In the 1980s, the US Army needed to be able to rapidly deploy a sizable force to face off against heavy forces. But that requirement created two problems: Most light forc
es were little more than speed bumps against tanks, and it took a long time to deliver a heavy force – and their supplies – to a likely theater outside of Europe or South Korea. So the Army began to explore ways to create a light force that could hold its own.
Enter the 9th Motorized, a force that proved it’s utility in several big
exercises during the mid-1980s, most notably in Border Star 85 when the 3rd Armored Cavalry Regiment lost badly to the 3rd Brigade of the 9th Motorized. The Army’s strategy seemed to be playing out in a good way.
But a change at the top of the Army detoured the promise of the 9th. The new Army Chief of Staff favored the light infantry division concept over the motorized division. Ultimately, four active light infantry divisions (the 6th, 7th, 10th Mountain, and 25th) were formed, with one more, the 29th, in the National Guard. Later, the 9th, as well as the 6th and 7th Infantry Divisions, were deactivated after the fall of the Berlin Wall as the budget ax fell.
