In the Documentation of the bfme2modsdk it says in the "Characters.htm" that the polycount is about:
LARGE MONSTER
MUMumakl_skn00.w3d (max. 8 characters prior to the underscore)
Normal: 2250 verts and up to three textures.
Medium: 1125 verts and one 256 texture. (approx. 60% of orig. vert. count.)
Low: 700 verts and one 256 texture. (approx. 35% of orig. vert. count.)
MEDIUM MONSTER

Though I didn't open the models to look up their polycount. Maybe this information can help you out however.
