Recognition Notes

The Sentinel STN-3M is a 40-ton striker, a 3035 field refit of the 2651-era STN-1S that trades reach for punch. Where the original scout mounted an AC/2 in the left arm, this version carries an Ultra AC/5 in the same location, and the SRM 4 in the right torso is replaced by an SRM 2 alongside a Medium Laser. Cruising and top speed hold at 65 and 97 km/h, and the heat-sink count drops from 12 single to 10 single. Enhanced communications gear carries over from the STN-1S, and the type is built as a field refit at various sites rather than at a single factory.
