Arcturus Defense Solutions Crowd Control SMG ACSM-3 'Shepherd'

The ACSM-3 Shepherd is a dual-feed SMG that accepts two magazines simultaneously — one loaded with lethal 9mm caseless rounds and one with rubber-composite less-lethal projectiles. The BCI fire-control system allows the operator to switch between lethal and less-lethal ammunition through neural command, selecting the appropriate response to each individual in a crowd without changing weapons or magazines.

The weapon's BCI overlay integrates with Arcturus' crowd-analysis AI, which categorizes individuals in real-time as passive, agitated, or hostile. The system recommends lethal or less-lethal response for each categorized individual, and the operator confirms or overrides per-target. In practice, a Shepherd operator can fire rubber rounds at protesters while switching to lethal ammunition for armed individuals within the same trigger squeeze.

Arcturus designed the Shepherd for corporate police crowd-control operations, replacing the two-weapon system (lethal rifle plus less-lethal launcher) with a single platform. At Φ5,500, the weapon is institutional procurement only. The dual-feed mechanism is mechanically complex and requires regular maintenance, but the tactical flexibility it provides has made the ACSM-3 standard issue for Arcturus crowd-management units.

specifications	caliber: 9mm caseless (lethal) / 9mm rubber-composite (less-lethal) effective_range: 50m (lethal), 30m (less-lethal) rate_of_fire: 600 rpm (cyclic) magazine_capacity: 20+20 rounds (dual magazine) weight: 2.7 kg
tactical use	The Shepherd allows continuous crowd-control operations with escalating force options available per trigger pull. Operators can suppress non-lethal threats with rubber rounds while immediately engaging armed threats with lethal ammunition, maintaining a single point of aim and eliminating the delay of weapon transitions. The crowd-analysis AI provides real-time threat categorization, but operators retain final authority on ammunition selection for each target.
cultural context	The Shepherd is the most visible weapon of corporate crowd control. Its dual-feed system has been criticized as enabling casual escalation — the ease of switching between lethal and less-lethal ammunition lowers the psychological barrier to lethal force. Protesters have learned to identify Shepherd operators by the distinctive dual-magazine profile, and the weapon has become a symbol of the corporate police state's capacity for selective violence within crowds.
known users	Arcturus corporate police Crowd-management units Civil unrest response teams
story hooks	A Shepherd operator's BCI was hacked to display all crowd members as 'hostile' — the operator fired lethal rounds into a peaceful protest before realizing the overlay was compromised. The crowd-analysis AI has been trained on biased data that categorizes certain demographics as 'agitated' regardless of their actual behavior, leading to discriminatory less-lethal targeting.
ammunition type	9mm caseless lethal 9mm rubber-composite less-lethal
physical description	The ACSM-3 Shepherd is a compact, angular SMG with a reinforced polymer frame weathered to a dull gunmetal grey, its surfaces scarred from field use. Twin feed ports run parallel along the receiver, each leading to separate magazine wells; the left chamber glints with brass casings visible through a scratched inspection port, while the right shows the dull composite rounds of less-lethal ammunition. A neural interface jack protrudes from the grip, its connector worn smooth from repeated use, and the weapon's handguard is wrapped in faded grip tape.
