SUPPLIES to AIR WINGS WTF (Little Upsilon)

Hey all - Supply Q. I set up 6 helecopter WINGS & I have 17M Air Fuel in stock & tons of trucks. Large & small Supply Units are attached to 3 Offensive bases - but my air wings ( 3) are dry - how do I get them fuel?? I can'y attach a Supply unit to them (I don't believe). Any help respectfully accepted.

Zanzia, probably you need to set up a few more supply units, though the ones you have will get aound to supplying the wings sooner or later.
If you are in urgent need for them to be fully supplied, dismantle them and set them up again and they will be fully loaded (to your blueprint) providing you have the necessary stuff in stock.
