{{Distinguish|Radically Invasive Projectile}}The R.I.P. cartridge (round irritant personnel) 12-gauge ammunition comprises cartridges filled with a mixture of micronized CS gas, an inert powder to add weight, and a further non-toxic powder which, on compression and friction, produces a large amount of carbon dioxide gas on exiting the barrel of the shotgun.

These specialist rounds are used in situations such as hostage rescue, where a less-than-lethal approach is required in order to resolve an incident.[https://clucas.com/ammunition/close-range-rip-round/ Ammunition – Close Range RIP Round Live and Practice]

Persons subject to the dispersed contents of an R.I.P. round will be incapacitated for a given amount of time, depending on the precise content of the round.
