npc_alien_grunt_unarmored is a point entity available in 
Black Mesa 2012. It is a variation of the alien grunt that uses only melee combat and never uses hivehand. It seems that initially this NPC should use the model that does not have armor or hivehand (which can be seen in the chapter Questionable Ethics), this is confirmed by FGD, however, it uses model of the classic version of alien grunt, probably due to incompleteness, or because the model doesn't work with this NPC properly (broken animations and ragdoll model). This NPC is not used in the original campaign; perhaps at some point it was intended to be used in earthbound levels. Was cut in 
Black Mesa since Steam release and and replaced by npc_alien_grunt_melee.
