M-113 BR Equipped with Ares' SARC Remax4 Tested at CAEx to Enhance Brazilian Army Capabilities.
On November 15, 2024, the Brazilian Army's Evaluation Center (CAEx) conducted a series of engineering tests on a technological demonstrator of the M-113 BR concept, fitted with the remotely-operated weapon station Remax4. This project, developed by Ares Aeroespacial e Defesa, aligns with requirements outlined by the Diretoria de Fabricação and the Arsenal de Guerra do Rio de Janeiro, representing a significant step in modernizing Brazil's military equipment.

The M-113 BR is an upgraded version of the M113 armored personnel carrier, widely utilized by the Brazilian Army. This version incorporates key improvements in mobility, protection, and firepower. Powered by a more efficient diesel engine, it delivers enhanced performance in various terrains. Its reinforced armor offers increased protection against ballistic threats and shrapnel. Standard armament includes a 12.7 mm heavy machine gun mounted on a remote-controlled weapon station, providing effective firepower while ensuring crew safety.
The M-113 BR is produced domestically, with upgrades carried out by Brazil's defense industry, including the Arsenal de Guerra do Rio de Janeiro. The modernization program aims to extend the operational life of the M113 fleet while meeting the evolving demands of modern combat. Enhancements such as advanced communication systems and night vision capabilities increase the vehicle's effectiveness and versatility for current mission profiles.
In early 2024, Ares proposed integrating the Remote-Controlled Weapon System (SARC) Remax4 into the M-113 BR armored personnel carrier. The technological demonstrator incorporates various upgrades, including the remotely-operated weapon station, optronic systems for the driver, an additional battery pack with smart charge management, a radio system for gunner data transmission and display, and a tactical computer compatible with the Proteus BMS (Battle Management System).

These additions improve crew and troop safety by enhancing situational awareness for the driver and commander in both daytime and nighttime conditions over extended distances. The Remax4 also increases firepower efficiency by reducing ammunition consumption and improving target accuracy. These advantages make the vehicle more effective in battlefield operations.
The Remax4’s design emphasizes functionality and ease of use. The gunner's station, located atop the vehicle, includes a retractable control panel with a firing joystick, optronic display, and essential controls. The system can be deployed and activated quickly. Meanwhile, the driver's position features a tactical screen on the left-hand side, allowing reliable navigation in low-visibility conditions and the ability to detect potential thermal signatures. This configuration enhances safety and efficiency during missions in challenging environments.
The system also includes controls for secure communications, weapon station operations, and smoke grenade launchers for self-defense. Additionally, provisions have been made for future integration of a software-defined radio (RDS-Defesa), developed by Brazil's Ministry of Defense, which will enhance tactical communication capabilities.
Considered an interim solution while awaiting the introduction of a new Infantry Fighting Vehicle (VBC FUZ), the M-113 BR modernization program is a pragmatic approach to optimizing the operational effectiveness of the Army’s most widely-used tracked armored vehicles. By incorporating the Remax4, the M-113 BR remains a valuable asset capable of addressing contemporary combat demands while extending its service life.
