CUBAN ARMY ORDER OF BATTLE
The Cuban ground forces consist of a standing Army of 75,000, a ready reserve of 100,000 and a heme guard of 100,000. The ready reserve is capable of being mobilized within a few hours. The home guard has only a very limited combat capability and in time of crisis probably would provide only local defense and rear area security.
Cuba is divided into three army areas — west, center and east. The highest operational echelon is the "division" which has an estimated strength of 3,000 - 7,000. Nevertheless, these "divisions" are not believed capable of conducting division tactical operations at this time. There are 22 "divisions".
The highest actual tactical echelon is the battalion which may vary from 500 to 1000 in strength. About 205 battalions have been identified, but many of these are home guard and ready reserve units and many are understrength.
