The art of war in the 21st century advancing to the multi-domain battle

Abstract

This research provides the examination of the current models of operations adopted by the Armies of the United States of America and Brazil, under the prism of War Theory. The research used a qualitative approach, examining two operational concepts - "Multi-Domain Battle" (USA) and "Full Spectrum Operations" (Brazil) - in order to infer the impact of the respective models on the application of Military Power of both nations. The study indicated that the American concept models a way of fighting that prioritizes a possible conflict of interstate bias, attentive to the advance of China, Russia, North Korea and Iran. It also indicated that the Brazilian concept combines offensive, defensive attitudes and cooperation/coordination with agencies, enabling the coping of fluid threats to security and defense. Finally, it was verified that both concepts form a way of fighting proper to the Land Military Power of each country, requiring specific capacities and investments.
