I read a epub version that didn't have the greatest sized maps, but was an excellent read (although some time spent learning soviet military maps should be spent to get the most out of it)
The conclusion draws some significant parallels to Russia's actions today with Ukraine.
"The elements of their invasion plan included the establishment of an in-country Soviet military and KGB element to assist the invasion force and the production of a cover or deception operation to divert attention away from the future invasion. A General Staff group would tour the country in advance of the invasion, under some pretense, in order to assess and fine-tune invasion plans. When the invasion began, the in-country Soviet military and KGB element would disarm or disable the national military forces. Airborne and SPETSNAZ forces would spearhead the invasion and seize major airfields, transportation choke points, the capital city, key government buildings, and communications facilities. They would seize or execute the key government leaders. Soviet ground forces would cross into the country, seize the major cities and road networks, suppress any local military resistance, and occupy the key population centers. A new government would then be installed, supported by the armed might of the Soviet Armed Forces.
This invasion plan was also used in Afghanistan. Soviet military and KGB advisers permeated the structure of the Afghanistan Armed Forces. In April 1979, General of the Army Aleksiy A. Yepishev, the head of the Main Political Directorate, led a delegation of several generals in a visit to Afghanistan to assess the situation. General Yepishev made a similar visit to Czechoslovakia prior to the 1968 invasion. In August 1979, General of the Army Ivan G. Pavlovski, CINC Soviet Ground Forces, led a group of some 60 officers on a several-weeks-long reconnaissance tour of Afghanistan. General Pavlovski commanded the invasion force in Czechoslovakia in 1968. The invasion of Afghanistan was launched on Christmas Eve, certainly not a Muslim holiday, but a time when the Western governments were not prepared to react. Soviet advisers disabled equipment, blocked arms rooms and prevented a coordinated Afghan military response. Soviet airborne and SPETSNAZ forces seized the Salang tunnel, key airfields, and key government and communications sites in Kabul. Soviet SPETSNAZ soldiers killed President Amin. The Soviet ground invasion force crossed into the country, fought battles with pockets of Afghan military resistance and occupied the main cities while the Soviet government installed their Afghan puppet regime.

So, initially the press carried pictures of happy Soviet soldiers building orphanages-and did not mention that they were also engaged in combat and filling those very orphanages. By the end of 1983, the Soviet press had only reported six dead and wounded soldiers, although by that time, the 40th Army had suffered 6,262 dead and 9,880 combat wounded. "
