The defence estate is divided as training areas & ranges (84.0%), research & development (5.4%), airfields (3.4%), barracks & camps (2.5%), storage & supply depots (1.6%), and other (3.0%). These are largely managed by the Defence Infrastructure Organisation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What percentage of the defence estate makes up training areas and ranges?
84.0%
