The difference between the two is that CCRP calculates the error between the impact point and the 'designated' target, and provides steering cues/release to hit that target, while CCIP just displays the impact point, allowing faster engagement of dispersed or opportunity targets with a reasonable degree of accuracy - errors in range may be greater as there is no 'pickle' on solution, and it relies on visual estimation of error... more than made up for by using multiple weapons, or CBU with a larger footprint...
