Yeah bedrolls... but they would sleep in them for all eternity!
MUAHAHAHAHA-
*Ahem* Anyway I think they're probably bedrolls too, or something else. But @STM I don't think they're are carrying body bags, because what they're carrying have a lighter color than the ones we see at the end of the video and those light bags don't have any zippers between the two codes on each one of them. The material looks different too.
