That troop has a BAR.
OK ... I had to do a little research.
The weapon is belt-fed and has a carry handle. For a BAR, that’s very unusual. Belgium and Sweden made such modifications. Given that those troops are RLI, I guess it’s probably the FN Belgium variant. But I’m not sure.
The guy on the right looks Australian.
The guy on the left is hauling the MAG so you can tell they are not in an Aussy outfit.
What they are wearing is not much more than rags so all things considered I would guess they are RLI, 3 Commando.
