Marc,
Its difficult because once you engage through an interpreter you get their interpretation. However, the BN S3 did speak english and he would generally say " my soldiers did this" or "the patrol, they do this".
I think there was some "we" and there was some "I" in the interpreters' responses - this may have also been skewed by how I asked the question(s) and which interpreter I used (not all are as capable - or as familiar).
If I had to strike a balance I would say that when referring to a "we" it was more along the lines of the patrol vs. a company or BN - this reflects how they operate - and maybe why I reflected that in the org chart I did up on "building Indig Sec Forces" in VOL 8 - I just did not fully realize why I did it until now - interesting.
Best, Rob
