One method touched upon by two bugs in the comments is that you can interrogate soldiers so they mark on your map where the "Specialist" soldiers are. If you're low on fultons, in a hurry, or being very particular, I highly recommend this strategy. Specialists typically have higher stats than their comrades, and there is usually at least one per camp.

You can interrogate soldiers through two methods:

1. CQC choke hold an enemy by pressing and holding the CQC button (default R2 on PS4 controller). Continue to hold this button then open the communication menu (L1, likewise).
2. "Hold up" an enemy, either by approaching stealthily and drawing your weapon at close range, or by drawing your weapon during a multi-hit CQC combo. Again, open the communication menu while maintaining your weapon draw to reveal the interrogation options.

There are two options, one will get them to mark on your map some nearby soldiers you have failed to already mark. The other will get them to mark a point of interest, be it some processed resources, rough diamonds, or their nearby specialist.
