A previous post saw Cuba’s November 9th announcement of its “Bastion 2016” military exercise as an immediate reaction to the U.S. election of Donald Trump. A Cuban source, however, rejects this interpretation. It says that such exercises are held every four years in November, that this year’s exercise was announced in April 2016 and that these exercises involve “the training and massive mobilization of troops, reservists and civilians throughout the island to face the possibility of military aggression, which already had a [U.S.] failed attempt in April 1961 [at the Bay of Pigs].” (Emphasis added.) In April 2016, however, Cuba knew that November 9th was the day after the U.S. presidential election.
The start of the defensive “Bastion 2016” military exercise on November 16 was celebrated in Granma, the official newspaper of the Communist Party of Cuba, which said it “will involve . . . the Party, the Government, agencies of the central state administration, enterprises, institutions and units of the Revolutionary Armed Forces, the Interior Ministry and the population. The exercise will consolidate the conception of the war of all the people and at the same time reflect a higher step towards strengthening the military invulnerability of the country.”
Moreover, according to Granma, the exercise will “demonstrate efficiency, conservation status and modernization of combat technique and inseparable part of the Cuba campaign that mobilizes our country and the world ‘against the economic, commercial and financial US blockade against our country.’” (Emphasis added.)
During the five days of the exercise, Granma brought reports of success from around the island and of its review by a meeting of the country’s National Council of Defense’s Social Economic Body, which was led by Raúl Castro and attended by several Politburo members, vice presidents, ministers and other government officials and top leaders of the Revolutionary Armed Forces and Ministry of Interior.
At the conclusion of the exercise, the Political Bureau of the Party’s Central Committee proclaimed that the objectives of the exercise were met across the country with quality and enthusiasm.
On November 19 and 20, Cuba celebrated the National Days of Defense with tactical troop maneuvers. For example, on the northwestern coast of the island the Western Army simulated a response to a hypothetical air and naval invasion with launches of anti-aircraft missiles while its Revolutionary Navy deployed special formations to obstruct the entrance to port facilities. Nevertheless “the adversary created the conditions for landing reinforcements and ‘capturing’ the bay.” However, the enemy was totally neutralized.
These public sources, however, do not provide sufficient details about the exercise that would enable an outsider to assess the quality and magnitude of Cuba’s defense capabilities.
