In the late 1970s the Pentagon began testing Assault Breaker — an experimental marriage of sensors and standoff missiles meant to find and strike armoured columns deep behind the front line. In Washington it was one prototype programme among many, its promise uncertain, its budget contested.

In Moscow it was read differently. Analysts of the Soviet General Staff gave the programme, in the words of the Israeli scholar Dima Adamsky, “far more credit than it deserved” — and out of that overestimate distilled a concept the Americans had not yet articulated for themselves: the reconnaissance-strike complex, the core of what Marshal Ogarkov called the military-technical revolution. The side that could not build the systems named what they meant.

The side that could build them took roughly a decade longer to see it. When American thinkers finally recognized the revolution in their own arsenal, Adamsky writes in The Culture of Military Innovation, they did so “by studying the reflections of American military power in Soviet eyes.” The instrument of the Soviet head start was not a laboratory but an institution: a General Staff that functioned as the brain of the army, paid to turn hardware — anyone’s hardware — into a theory of victory. The United States had the hardware and, for a decade, no organ tasked with asking what it added up to.

Then the twist that keeps the story honest: the Soviets saw first and still lost. Adamsky’s verdict is that they were “pathologically bad at connecting words and deeds” — conception without production proved as barren as production without conception.

A technology and its meaning are separate assets. They sit in different institutions, and sometimes in different countries — and nothing guarantees that the power fielding today’s systems is the one that understands what it has built.
