Something tells me that they are not entirely mercenary.

Actually most modern mercenaries aren't entirely mercenary. Back during the Cold War, there were lots of mercs who'd fight for any anti-Communist regime that paid them enough, but only for anti-Communist regimes. I suspect more or less the same lot will now fight counter-jihad, and only counter-jihad, again for enough pay.
