Question about Space Marine supply lines in battle

Is there anything in the lore to explain their battlefield logistics? For example, SM only carry a limited amount of ammo and they can go through it quite fast. Who runs ammo to the frontlines? Do they make do with what they have? Do they withdraw once supplies run down?

I'm reminded of the Battle of Zion scene from Matrix Revolutions where dudes with carts run out in the middle of the fighting to carry ammo to the battle suits. The thought of chapter serfs doing the same thing for SMs amuses me.
