For the 40mm impact munitions in the list. Riot control gear.

“Grenade launcher” here isn’t very specific. Could be like an M203 or something, which is a tube launcher that lobs 40mm rounds up to about 100m. You can absolutely get 40mm frag grenades and blow shit up, that’s what most people think of when they think of a “grenade launcher,” but that’s not what it’s on the list here. You can lob gas canisters, smoke, illumination flares, etc etc etc, just depends on what you’re trying to do.
