I dont know about you...but I didn't face these things, and they are in the hl2 model folder. heres some pics. one is the thing breen talks to, but it has attack animations in hl2 model viewer, and it never attacks anything ingame. One you see while taking the citadel ride at the end, they are marching below you, they also have attack animations, but never do ingame. the other one that flys in the animations Ive never seen before, Its named mortar...
