APPRAISAL OF CUBAN AND SOVIET MILITARY STRENGTH IN CUBA

Since the missile/bomber crisis of October 1962 and the subsequent
withdrawal of Soviet strategic weapons and associated personnel, the
military posture in Cuba remains essentially a significantly improved

and coupled with the fact that no basic changes have been observed in the
Soviet military establishments in Cuba, we have not yet revised the estimate
of Soviet military strength as being in the magnitude of 17, 000.
We have no indications that Soviet personnel and equipment are being
withdrawn from the four Soviet military camps at Holguin, Remedios,
Artemisia, and Santiago de las Vegas.. About 5, 000 Soviet troops have
been estimated to be in four highly mobile armored groupings at these
camps, well equipped with modern, sophisticated weapons, and about 5, 000
involved in the 24-site SA-2 missile system. The remainder are manning

to Cuban ground, air, and naval units as advisors and.nstructors. There

phasing of the projected Soviet troop withdrawal are not yet clear. How-
ever, Moscow apparently hopes to maintain a sizable military presence
in Cuba. The Soviets probably calculate that such a military presence

The capabilities of the standing army and ready reserve have been
enhanced by new equipment brought in during 1962 and by further training

lends credence to such a potential. On balance, however, it is difficult
to envision circumstances in which either the Castro regime or the Soviet-
authorities would find such a course of action to their advantage. Never-
theless, the defenses of Southeastern United States have been significantly
strengthened.

The time required to overthrow the Castro government cannot be

may cause the collapse of organized Cuban resistance. However, plans
are based on the worst possible. outcome of the initial operation, namely,
Cuban reaction is such that the initial US assault forces must await
reinforcement before proceeding with assigned tasks. Based on estimated
Cuban capabilities, it is possible that major combat operations might
