The letter argued that the site is far more than a sports facility. It said the station supports over 5,000 personnel with accommodation, training areas, a medical centre and a school, and carries counter-unmanned aerial system duties coordinated by the Delhi Integrated Air Defence Centre. The IAF has used the land since the 1940s, and the letter described it as critical to operations. The location adds weight to the argument, since the station sits near the Prime Minister's residence, which makes air defence of the area a live concern.
