Broken attachment points?

[Wayshan]

Hey, so I wanted to add some backpacks to these soldiers and failed, their attachment points seem to be broken. Can anyone take look and help me out?

Well, this sounds like something for the request section. It all depends on the scaling of the models and their attachment points.
For a backpack, I would assume "chest" is the attachment point.
If the scaling is out or the units don't have that attachment point, then you'll have to delve into the realm of 3D modeling and add/change them manually.
You may even have to move the center point for the backpack itself in a 3D model editor to suit your fancy.
