It's an interesting and fairly easy read, but should be taken with a grain of salt. Rezun was a captain in Soviet military intelligence (GRU) who defected to England in 1978 with his family. Rezun provided much intelligence to western planners, some of which came into dispute under later examination. Notably, many feel Rezun overstated the capability of the Red Army in the late 70's and early 80's, leading directly to the Reagan-era military buildup to counter a much larger threat.
