In 2015, the U.S. Army and Marine Corps began fielding the new type of M777 155mm artillery, a much smaller, lighter, and more maneuverable towed cannon weapon than its predecessor, resulting in improved transportability and mobility without impacting range or accuracy. Seven-Ton trucks are used to move the M777s, enabling artillery units to move faster between positions.
Philippine Marines 105mm howitzer
The Philippine Marines also conduct simultaneous 105mm howitzer firing. With the combination of 155mm and 105 mm Howitzers, both armed forces can maintain a high level of readiness and responsiveness and enhances combined military-to-military relations, interoperability, and multinational coordination.
For the Philippine Army, these skills are typically used in operations to lessen the risk of infantry and to destroy targets.
