In the Amazon region, the military conducted large-scale simulations in Roraima involving over 1,100 personnel. These exercises utilized modern equipment, such as smart sensors integrated into helmets and vests, to adapt traditional jungle reconnaissance to modern battlefield realities involving aerial surveillance and electronic warfare. Simultaneously, the Army has made progress in technological certification and testing. This includes successful firing tests of the Tactical Cruise Missile (MTC) for the ASTROS Artillery System, which can strike targets up to 300 kilometers away. Further advancements include the testing of the SENTIR M20 Ground Surveillance Radar by Embraer, capable of detecting small drones at distances of 4 kilometers, and the integration of anti-drone defenses and satellite communications during Operation Sagitta Primus. ## Timeline ### 2026-08-27: Brazilian Army advances defense tech with missile and radar tests The Brazilian Army and domestic companies Avibras and Embraer have successfully tested new defense technologies, including a tactical cruise missile and a drone-detecting radar. 4 sources. https://clstr.news/cluster/brazilian-army-advances-defense-tech-with-missile-and-radar-tests ### 2026-08-22: Brazilian Army conducts advanced jungle warfare simulations The Brazilian Army is conducting advanced military simulations in the Amazon, utilizing smart sensors and drones to adapt jungle warfare doctrines to modern battlefield technologies. 2 sources. https://clstr.news/cluster/brazilian-army-conducts-advanced-jungle-warfare-simulations --- Cite as: Brazilian Army modernization and defense testing.
