There was a lot more "combat" loading of LKA/AKA, since they were a bit more purpose-built to the task.
Admin versus Combat loading is some tough study, too. You have to load the holds in combat loading on first = last out. What is last om = first off, has to be coordinated with the commander of the land forces, too. Oh, and you have to preserve the ship's stability through all this, too.
And also balance the loading versus the number/capacity of the landing craft you have, too.
The beachhead commander will want his armor and artillery as soon after the infantry lands as possible, too. In WWII, you could get some balance there, for having a number of light tanks type available.
In one of those counter-intuitive things though, you need to unload the tankers and artillery ammo trucks first. They drive slower to the rally points, so they have to start sooner.
This is even more fun in modern times with helo support. You send the ground support & maintenance team, along with the fuel bladders before you even wake the aviators up.
It's a fascinating subject, and one that will continually challenge a person.
