how does one transfer ammunition to a anti-tank gun

[happy]

Hi there,

I have ordered men of war and have been playing around with the demo.
And sofar I'm enjoying this great game! I find it very refreshing and fun to play, can't wait to get the full game.

I have a Q though? I haven't had any luck transferring ammunition.

I can put two men on an anti tank gun, drop the shells on the ground
and let it be picked up by another soldier, yet when I wish to transfer the shells to a truck or a other anti tank gun then I seem to have no luck.

I can only manage to drop the shells on the ground near the soldier instead of putting them in the inventory of a gun or truck!

How does one perform such a task? can it be done? how?
