Although concealment and misdirection of adversaries are primordial acts, the word “camouflage” did not enter the English language until World War I. Author Nicholas Rankin observed in his book “A Genius for Deception” that “the Oxford English Dictionary’s first example of published usage is from the Daily Mail in May 1917: ‘The act of hiding anything from your enemy is termed “camouflage”.'”
Nearly a century later, there is a full-fledged theory of camouflage, which is neatly presented in a new U.S. Army manual (pdf). The theory carefully distinguishes among related techniques such as hiding, blending, disguising, disrupting and decoying, each of which means something different.
The manual provides practical advice. When selecting foliage for camouflage, “coniferous vegetation is preferred to deciduous vegetation since it maintains a valid chlorophyll response” — against an enemy’s infrared sensors — “longer after being cut.”
And it reflects the lessons of experience. “Warfare often results in personnel losses from fratricide. Fratricide compels commanders to consider [camouflage’s] effect on unit recognition by friendly troops.”

There is no better time to re-invigorate America’s innovation edge by investing in R&D to create and capture “industries of the future,” re-shoring capital and expertise, and working closely with allies to expand our capabilities while safeguarding those technologies that are critical to our security.
Russia currently maintains nearly 5,460 nuclear warheads, with an estimated 1,718 deployed. This represents a slight decrease in total warheads from previous years but still positions Russia as the world’s largest nuclear power alongside the United States.
The stakes are high: how we manage this convergence will influence not only the pace of technological innovation but also the equity and sustainability of our energy future.
We’re launching an initiative to connect scientists, engineers, technologists, and other professionals who recently departed federal service with emerging innovation ecosystems across the country that need their expertise.
