In my opinion I think Konni PMC is stronger. The only time shadow Company managed to beat them was in the first mission of mw2 when they launched a cruise missile targeting an Iranian general who was smuggling weapons to Al Qatala which were funded by Konni Ultranationalists. In modern warfare 3 Shadow company destroyed the Konni base with an AC-130 however I don’t remember Shadow sending any troops on the ground to support Taskforce 141 and ULF forces who were searching for Makarovs gas. Other than that almost every other engagement the Konni whooped there ass.
