Air pressure
No. Not at all. Volume has no force. Put 1 cubic foot of air inside a sealed jar, and weigh the air. Now let the same air into a 10-cubic-foot jar; seal the jar, and weigh the air again. The air has 10 times the original volume, but it still has exactly the same weight.

The atmospheric pressure at that place and at that time.
Atmospheric pressure.. maybe
Resistance from air.
If the Air Force didn't destroy the army, they could sure isolate the army from any re-supplies; and starve an army to death. The Air Force can fly away, the army's stuck on the ground. WEll PUT SIR!!!!! WE'LL END YOU
