Recognition notes
The ON1-H is a 75-ton brawler, a 2456 rebuild of the 2453 ON1-C original. Where the ON1-C carries a single AC/5 in the right torso, this variant mounts a Primitive Prototype Autocannon/10 in its place, and the left arm's medium laser is joined by an SRM 4. Twin LRM 5 racks fill the left torso, weapons the base configuration does not carry. A lighter 270 fusion engine replaces the ON1-C's 360, cutting cruising speed from 43 to 32 km/h and top speed from 65 to 54 km/h. The design is still marked as an easily-serviced machine, though listed as obsolete by 2525, and General Mechanics builds it at Mars.
