Do you think these guys enjoy having a photographer following them around? I think I'd probably want to smash the guy's camera (at least).
Hmmm, about 100 lbs to 120 lbs in most cases, probably a little a more in somes cases. Now, that includes their rucksacks (backpacks), which you can clearly see in the photo that shows them being dropped off by a Chinook. Each of those rucks probably weighs 60 lbs to 80 lbs.
The guy to the right of the Chinook leaning over a little is carrying a radio, you can see the antenna sticking out of his ruck. Now, that's a heavy ruck.
I know from experience, (7th ID Light).
Well, the Army does have a Combat photography unit to document battle. They could be from one of them and selected pics given out to the press.
I don't know if that's the case here, but it could happen in such a way.
