Interesting stuff! Reminds me of an episode I was involved in 20 odd years ago. Only this time, the human cargo was Muslim civilians, not fighters, and definitely not those jihadi headbangers that were around even back then.
The deal was to try and transport them, in trucks, open backed as well as box / fridges, out of Srebrinica before the Serbs got to them. Sad to say, in the end, after spending all day on the front line, it didn’t happen. We all know how that ended up.
