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.
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.
On 9th June 2008 English firearms officer PC Ian Terry was accidentally shot and killed by a R.I.P. round fired by a colleague whilst on a training exercise.
