I've downloaded this tag by JokeyMod, and it was successful.
However, when I use it in sapien, it says I'm missing a tag, and sure enough, I think I am.

file_open('tags\characters\marine_armored\marine_armored sarge.gbxmodel') error 0x00000002 'The system cannot find the file specified. '
couldn't open gbxmodel tag 'marine_armored sarge.gbxmodel'.
failed to load biped tag 'characters\marine_armored\marine_armored johnson'

here's the link to the download:

What should I do to get the gbxmodel?

Well, I haven't downloaded the tag, so I wouldn't know. However, it's easy to make your own.

1) Find characters\marine_armored\marine_armored.gbxmodel
2) Save it as marine_armored sarge.gbxmodel
3) Open it in Guerilla
4) For the region arms, check "cannot be chosen randomly" for the _base permutation
5) For the region head, check "cannot be chosen randomly" for all permutations except the johnson permutation.
6) Save
7) Reference in your biped.

I'm a noob so, I don't really get #5, and what do you mean by "reference in the biped"?
thanks

Open the .biped, and at the top, where there's a path for the model, click the 3 dots and browse to marine_armored sarge.gbxmodel.

the model 'characters\marine_armored\marine_armored sarge' and the collision model 'characters\marine_armored\marine_armored' don't match (region counts don't match)
the object 'characters\marine_armored\marine_armored johnson' will not be collidable

this is my debug
