Jamming.

From the Internet web site Space Review and interesting article.

During that era of the Vietnam War the proverbial intelligence goldmine from an unexpected source and under unprecedented circumstances.

"The wizard war in orbit (part 4)" by Dwayne A. Day

"In August 1968, Soviet forces invaded their captive ally Czechoslovakia. The invasion began with an intense electronic warfare campaign against the Czech air defense network . . .  'Jamming apparently was not targeted in the radio frequency range of NATO radars; the locations of chaff seeding suggests that it was not intended to screen Soviet air operations from Western observers.'”

. . . .

"some of the jamming might have been directed at the SA-2 surface-to-air missile fusing system—a subject of considerable interest to the American military because SA-2 missiles had been blowing American combat aircraft out of the sky in Vietnam. Other jamming might have been intended for land-based guided missile systems that could have been fired at invading Soviet forces. The electronic warfare effort was successful, the Soviet invasion took place without a hitch"

"this would have been an intelligence bonanza for the United States military, because the Soviets understood best how to jam their own equipment, and monitoring what they were doing in Czechoslovakia could have provided information that the American military could use against similar weapons systems in Vietnam."

The "proverbial intelligence goldmine", the "intelligence bonanza" AND AS ESSENTIAL TO THE AMERICAN AERIAL BOMBARDMENT OF NORTH VIETNAM!

WE HAVE TO BE 100 % CRYSTAL CLEAR ABOUT THIS! THE SOVIET JAMMING THEIR OWN SYSTEMS AS SUPPLIED TO THE CZECH. AMERICAN INTELLIGENCE ABLE TO MONITOR THIS EFFORT THAT KNOWLEDGE AS GAINED PROVIDING VALUABLE INSIGHT "THE AMERICAN MILITARY COULD USE AGAINST SIMILAR WEAPONS SYSTEMS IN VIETNAM"!

Who would have thought it?
