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 Brazil and Saudi Arabia in 2025.

ТThus, Brazil leaves behind Saudi Arabia by the number of soldiers in the service and by its 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, Brazil with its GDP of 4735 billion dollars (which was calculated by purchasing power parity) surpasses Saudi Arabia with its GDP of 2109 billion dollars in times.

Brazil and Saudi Arabia send 0,55 % and 3,55 % of GDP to the military expenses, respectively. As a result, the military budget of Brazil is 26.2 billion dollars and of Saudi Arabia is 74.8 billion dollars.

Hence, the military expenses of Saudi Arabia are times higher than in Brazil.

The comparison of armament     up↑

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

Brazil and Saudi Arabia have naval forces. The total displacement of the military fleet of Brazil is 80,9 thousand tons, Saudi Arabia - 28,9 thousand tons.

The comparison by the combat power index    up↑

While contrasting the armed forces of Brazil and Saudi Arabia 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:

● Brazil - 11 position in the world according to the combat power index 0.2415;

● Saudi Arabia - 24 position in the world according to the combat power index 0.4201;

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