This is the exact format of the w3d file armyantsm_gm01.w3d. I don't understand the first entry yet but I can tell you the subs.
Sub #0: HIER 0 716.
The first node at the first level in the w3d structure. It contains hierarchy data (the objects you select export tranform in renx). It starts after 0 bytes in the w3d file and has a total size of 716 bytes.
Sub #1: ANIM 716 8724
The second node at the first level and this one contains animation keys that are set on nodes in the hierarchy (that's why that one always comes before animation). It starts after 716 bytes and has a total size of 8724 bytes.
I can continue for the other parts listed but I think you get the drill. It is very easy to read through the nodes at the first level and get their type and size so we should be able to replicate this.
Just to complete it, MESH is a geomerty object and HLOD contains the hierarchal level of detail. It is only used by Renegade (and maybe earth and beyond?) but it also contains links between geometry and hierarchal objects.
