The US military talks about the two times it has been done since WW2.
The First Offset began during the early 1950s at the start of the Cold War. The Soviet Union had a geographical advantage over the U.S. in Western Europe and had a far larger conventional force of tanks. The USA used nuclear superiority to counter. Nuclear weapons were miniaturized to about the size of a football. The Soviets were able to match US capabilities in about ten years.
