when you look on the Stranded mission, you see one of those ''robots'' coughing up blood... so, I dont know how you worked that out genius.
( no sarcasm meant )
I think what he is trying to say is that the helmets prevent the audience from seeing the expressive facial features of the standard COG soldiers. This serves to make them faceless and disposable.
It wasent carmine it was just a random cog soildier like the one who gets killed by berserker just after kims death. Just before that another gets killed in the huge firefight when kim dies and then the captured dude at end of Act 3. They are just put in random soildiers dying with helmets on so you dont feel much pity for them. Its a clever little pchycological trick if you dont now them well and you dont see their face you dont really care much if something bad happens.
