The armies’ comparison by the size

The army size directly depends on the country’s population and its mobilization potential. In the table below there is the information about human resources, mobilization potential and armed forces size of Cuba and Eritrea in 2025.

So, Cuba is inferior to Eritrea by the number of soldiers in service, although it surpasses by the mobilization potential.

Let’s note that the above mentioned data show only the quantitative characteristics without taking into account the professional level of military personnel and the quality (basic skills, physical condition, etc.) of the mobilized and conscripts.

It’s more difficult to estimate such parameters as motivation, combat spirit and soldier’s steadfastness, the ability and wish to perform their duties up to the end.

The comparison of military budgets    up↑

The military financing greatly depends on the country’s wealth – the stronger the economy is developed, the more finance can be allocated for the military expenses. As for the economy size, Cuba with its GDP of 137 billion dollars (which was calculated by purchasing power parity) surpasses Eritrea with its GDP of 7,64 billion dollars in times.

Cuba and Eritrea send 3,29 % and 2,59 % of GDP to the military expenses, respectively. As a result, the military budget of Cuba is 4.51 billion dollars and of Eritrea is 0.198 billion dollars.

Hence, the military expenses of Cuba are times higher than in Eritrea.

The comparison of armament     up↑

In the table below there is the information about some types of armament which are at the disposal of Cuba and Eritrea (we account the total amount of weapons in 2025, without considering modifications, the year of release and departmental affiliation):

The comparison by the combat power index    up↑

While contrasting the armed forces of Cuba and Eritrea one can orient on military strength ranking from GlobalFirepower (GFP). The GFP experts have analyzed more than 60 different factors which affect the defense ability of different countries and the effectiveness of their armed forces. As a result, they have calculated the combat power index. The lower it is, the stronger in the military sense the country is.

As of 2024, the countries under consideration take the following positions in GlobalFirepower rating:

● Cuba - 67 position in the world according to the combat power index 1.3286;

● Eritrea - 120 position in the world according to the combat power index 2.6985;

Thus, according to the GlobalFirepower, the more combat-ready are the armed forces of Cuba.
