RA3 areas tend to be live firing, which in most cases can be knocked off in the event of an aircraft experiencing an emergency. In some cases e.g. Puckapunyal, for URGMED flights or in the event of diversions due TS, to assist ATC traffic management the Army often hold activity.
With Prohibited Areas (and we don't have any), aircraft are not permitted under any circumstances. Full stop.
