Something makes me think not. You can see the piece of loot has a radio, flamer fuel and a flamer itself. You can see that none of the enemies died by flamer - all of the bodies are still intact (well, kind of) and none of them are burnt. Very rarely people take radios, so it may be a piece of loot after battle. Also, when someone or something explodes all their inventory is dropped on the ground. You can see that is the only piece of loot in the whole screen, which could mean he dropped off all the loot there.
