Try removing the MG stuff from the gunner and put commonmeshes.abp there instead.
Although it should still work with how you are doing it, here is how I have mine setup:
data\art\models\soldiers\german\heer\grenadier.abp
Code:model = { -- common [[..\..\..\Races\Common\CompleteMotionTree.abp]], [[..\..\..\Races\Common\CommonMeshes.abp]], -- weapons [[..\..\..\Weapons\German\Small_Arms.abp]], -- main mesh [[Grenadier\Grenadier]], }
