How do I use the Ammo trucks?

[Velineon]

In a recent match I ran out of ammo for a tank, and I bought the ammo truck. Unfortunately, I had no idea how to actually use this ammo... lol Do I have to get out of the truck or what? Thanks!

select ammo truck -> press "eye" icon -> klick refuelling unit -> ammo truck drives near refuelling unit -> both inventar should be shown -> doubleklick/move ammo y need.
