He's looking for two pucks, what's he looking for exactly?

The dictionary definitions of puck is a disk used as a “ball” in hockey and computer mouse.

Now, the “good soldier” has taken some guy from his house and is doing some interrogation in the outside while the “bad soldier” comes into the scene by helicoper and asks the “good soldier” for the other two pucks that are seem to be missing. (In the subtitles it is written as puck and not pack. The word puck is not mentioned again in the movie). What does he mean?

After this scene, a fight between the two “soldiers” ensues and the the bad guy takes the iraqi with him and leaves with the helicopter. He doesn’t seem to have taken with him anything else. So what are those other two pucks?

I don’t think he says ‘pucks’ though it is hard to work out what he does say.

Are you sure?

I still don’t think so - but if he does say that, then it’s a local slang US term, certainly not widely known.
Perhaps definition 11 here covers it.

Sounded as if he said “punks”.

Oh, well done Cristina. That would make much more sense.
