The ShieldTech SB-3 is the defining image of private security in GLMZ's middle tiers — a matte-black polycarbonate baton, 58 centimeters long, with a rubberized grip and a pair of exposed copper-alloy contact prongs at the striking end. It delivers a standardized 50,000-volt, low-amperage shock on contact, enough to cause involuntary muscle contraction and temporary incapacitation in most unaugmented adults. The SB-3 charges via a universal inductive pad in roughly four hours and holds enough charge for approximately forty full-power discharges before requiring a cycle.

The SB-3 has been in continuous production since 2161 and has undergone six incremental revisions, each improving ergonomics and discharge reliability without dramatically altering the product's essential character. It is certified under the Meridian Municipal Security Standards MMSS-7 framework, meaning it is legal for licensed security personnel to carry on duty. Off-duty carry requires a standard Tier 2 personal protection permit. The weapon is deliberately simple — no digital components, no wireless connectivity, no firmware to exploit or brick remotely. This is widely regarded as a feature.

ShieldTech markets the SB-3 almost exclusively to building security firms, transit enforcement contractors, and small-business owners in Tier 2 and Tier 3 zones. It is not glamorous. Security trainers across the city use it as a teaching tool precisely because it is predictable and honest about what it is.
