Martin looked trough the windows as he waited. Trough one of them he saw the guy he figured was in charge of this outfit, until he saw the target engage with big gun man. Suppose I'll refer to him as the boss then. But what do I call the other one then? He was smoking a cigar before wasn't he? Yeah, I'll call him smokes for now.
Hey what are you doing? The Internal Monologue can't just switch from 3rd person to 1st person! You are one to talk you just made it a dialog!

Martin groaned, he had a headache. Better?

Anyways, 'Smokes' was talking to another SOLDIER, blond kid. What caught Martins attention was that they where drinking coffee. He wanted coffee so badly now.
All he had on him were candy bars and blood-bags. And believe me there's no taste more bitter and disgusting as the combination of blood and chocolate.
