I want to know the answer to the following question:
What makes up the smallest portion of the defence estate?
All the background I'm provided with is that "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%).". Is that enough to answer the question?
Answer: yes
