Recognition Notes
The Stealth STH-3S is a 45-ton scout built off the 3054 STH-1D striker, riding the same 315 XL fusion engine to a cruising speed of 76 km/h and a top speed of 119, with a MASC-boosted sprint of 151 km/h and a jump range of 210 metres. Where the STH-1D carried an SRM 6, twin medium lasers, and a Streak SRM 2 spread across its torsos, the STH-3S trades that battery for a single ER PPC in the right torso. The left torso pairs the MASC with a Guardian ECM suite, and the Beagle active probe of the STH-1D is dropped from the loadout. Stealth armor replaces the STH-1D's standard plating, and the heat sink count climbs from 10 to 11 double. General Motors builds it at Kathil.
