Recognition Notes
The Sentinel STN-3L is a 40-ton striker built on the same 240 fusion engine as the STN-1S it follows a year later, cruising at 65 km/h and reaching 97 at full throttle. Where the STN-1S carries an AC/2, this configuration mounts an Ultra AC/5 in the left arm, and a Streak SRM 2 in the right torso replaces the earlier SRM 4. The Small Laser in the right torso carries over unchanged, though the heat-sink count falls from 12 to 10 single. Both variants retain the enhanced communications gear, and Defiance Industries builds the STN-3L at its Hesperus II works.
