It could be like Project Nova from Blops, where both the Russian 3rd Shock SO and the British SAS were after the nova 6, and although they weren't at war with eachother, they ended up killing eachother.

But in this game, it's probably PLR intel or plans or whatever, not a non-existent chemical agent.
