In the late 1950s, the United States adopted the ill-fated Pentomic Division layout of organization for its army. While going through declassified CIA documents, I found that (assuming the CIA document is accurate, the necessary caveat) around the same time, the Soviets were seriously considering adopting a similar model with a similar justification. The document in question is here.
Here’s the important picture. The proposed “Soviet-Pentomic” structure is on the left.
The big thing that makes the two similar is skipping conventional battalions in favor of regiments/”Battle groups” with a large number of companies in them. I thought it interesting at any rate, a minor footnote in organizational history.
