Non-Lethal. This weapon or piece of Equipment utilizes a Type of Ammunition that does not cause Damage, or does not require its target to make ARM or BTS Rolls when hit. Shock Special Ammunition Roll After a successful attack using Shock Special Ammunition, the target must make an ARM Roll. Effects Each ARM Roll failed against Shock Special Ammunition causes the target to lose one point from his Wounds/STR Attribute. If the target has a Wounds Attribute of 1 on his profile and fails an ARM Roll against Shock Special Ammunition, then he enters the Dead state directly, bypassing the Unconscious state. This specific special effect does not apply to: Units whose Wounds Attribute is higher than 1 on their profile (such as Heavy Infantry). Troopers who, during the course of the game, increased their Wounds Attribute above 1. Units with a Structure (STR) Attribute instead of a Wounds Attribute, such as Remotes, TAGs, Vehicles, etc. Against these, Shock Special Ammunition has the same effects as Normal Ammunition. Riotstopper uses Adhesive ammo, which forces a PH-6 roll on the target and does not deal damage. There is nothing in the rules that would make Shock ammo Non-Lethal. Strictly by RAW I would say that Marksmanship on a Riotstopper would make it Adhesive+Shock, forcing a PH-6 vs IMM-2 and an ARM vs a wound on hit. EDIT: I lied. MARKSMANSHIP LEVEL 1 AUTOMATIC SKILL Optional. REQUIREMENTS The user may only benefit from this Special Skill when he declares a BS Attack. EFFECTS In addition to their usual Ammunition, all BS Weapons wielded by the user have Shock Special Ammunition. The benefits of Shock Special Ammunition granted by Marksmanship are added to any other Special Ammunitions employed by the BS Weapon. However, these benefits do not apply to BS Weapons with any of these Traits: Throwing Weapon, Technical Weapon,and Non-Lethal. The last bullet point proves me wrong, so Armihaul is correct. Marksmanship does not work with Non-Lethal weapons.
http://infinitythewiki.com/en/Riotstopper Riotstopper (the weapon) is Non-Lethal, ammo type it uses is irrelevant. (Edit; sorry, just noted the last edited line)
