Tactics for fighting enemies in Iram of the Pillars

Are there any good tactics for fighting the "fire" enemies in Iram of the Pillars? I'm having a lot of trouble with them, particularly in the first fight after you get drugged.

Solution 1:

There are a few "heavy" weapons scattered about in these areas that will make the fights easier. After the area with the elevator, there is a RPG you can grab near the cover directly in front of you.

In the last area that's quite large, it can be challenging to avoid being killed over and over as you aren't afforded much cover initially. However, there is a RPG on the left side that you can quickly run to which will help you dispatch some enemies, as well as a M32-Hammer right in front of the door that will open after you clear this area.

Solution 2:

I found it reasonably easy to kill them using the sniper rifle or scoped pistol (Tau Sniper). It only takes 1-2 hits to kill them. If you can take them out quickly and keep some space between yourself and them, then in most cases you only have to deal with 1-2 at a time and they won't get a chance to damage you.
