MSAC International is a high-tech company that specializes in computer systems, sensors, and other electronic equipment. They are a complete subsidiary of GA, and due to their extremely high technology standards they single-handedly carry a large portion of the group's corporate value. They provide extremely specialized armaments, and control an overwhelmingly large share of the missile weaponry market.

Part CharacteristicsEdit

MSAC International produces nearly every variant of missiles available in the market. As such, MSAC provides a wide range of available missile weaponry, ranging from series-fire barrage missiles such as WHEELING series and MUSKINGUM shoulders, to high agility precision missiles such as POPLAR01 High-Act missile and OSAGE03 Enhanced Guidance Vertical Missile, and cluster/multi missiles, such as White Glint's SALINE05s. Besides missiles however, MSAC International also produces one radar unit, the MARIAS02. The radar is bulky and performs poorly when compared to other units however.
