Compare this unitRecognition Notes
The ON3-MX is a 75-ton heavy that fights at long range, a 3075 rebuild of the 2453 ON1-C brawler. Where the original carried an AC/5 and two Medium Lasers, the ON3-MX mounts an Improved Heavy Gauss Rifle in the center torso, an Extended LRM 10 and an ER Medium Laser in the left arm, and a second ER Medium Laser in the right arm. A 300 XL fusion engine replaces the 360 fusion powerplant, holding the same cruising speed of 43 km/h and top speed of 65 km/h despite the lighter engine, and standard armor now covers a frame once wrapped in primitive plating. CASE lines the left torso, and the type carries anti-aircraft fire control along with the rugged, field-serviceable frame the chassis is known for. Kali Yama/Alphard Trading Corp. builds it at Kendall.
