It's insane.
They're asking for/getting 110 litres per day for the airfields (3300/30=110 and 23000/7/30=~109.5). Either 10 litres for 10 pilots or 1 litre for 100 personnel. That'd fit in any car. Even x10 is only an IBC of water.
I suppose if the tankers/logistics are busy getting 1 litre to the thousands of front line troops they can't be spared for extra trips to the airfields.
