If you're using the editor, and you place a soldier (such as 'Light Machine Gunner'), but want to edit their loadout slightly, you have to know what item types they're holding and use the init line for it all.
For instance, you have to know what type of ammo they have if you want to add/remove it, and you can't tell at a glance if they have binoculars or NVGs.
Perhaps they could be added to the Virtual Armoury? Then you could just load up a light machine gunner, test them out, modify their loadout, and put them into the editor.
