How to unlock the Chemical Warfare achievement in Rise of the Tomb Raider - Definitive Guide
Stay to the left of the map as much as possible without alerting the enemies until you discover a new base camp. Swim underneath the ice, and drown the first enemy standing next to the opening using a water finisher. Get out of the water, and kill the second guy.
Immediately turn around, and shoot a poison arrow in the large group of enemies standing next to a red truck. *Achievement unlocked!*
You can restart the checkpoint at the base camp as many times as you need.
Here is a video of me getting the achievement:

I had a pretty easy time getting this right near the end of the game, when you are
Konstantin will call in a whole bunch of Trinity soldiers that will make a beeline for wherever you are. If you go up on the upper level, there are two wooden balcony-like structures that are behind an open archway in the stone walls. If you wait here on the balcony, soldiers should come up from both ends and bottleneck in the archway. Hide behind the arch, dodge around and wait for 5 to show up, then fire a gas arrow at their feet.
Dazu hab ich dieses kleine Video inkl. Erklärung gemacht ich hoffe es hilft euch
Via Expeditions mode, you can do this against the first group of enemies in the chapter "The Acropolis". Alert the enemies by getting detected or shooting up the place, then go back to the tent where you came from. Hide behind the box near the tent and let the enemies come to you. There should be 5 or more very close together. You can also shoot an arrow in their knees to slow them down. Poison Arrows can be crafted using normal Arrows, mushrooms and cloth.

Poison arrows can be very powerful if used well, killing a whole group of enemies with a single arrow. If you've not unlocked this during your main playthrough, I'd recommend attempting it on "The Acropolis" in Expeditions Mode. Here, when you reach the first group of enemies, fire a few unsilenced shots into the air to alert them, then run back towards the tent near to the path that you've come down and wait for the enemies to follow. With a little luck, you'll find that they cluster together, presenting a perfect opportunity for a poison arrow into the middle of the group to unlock the achievement. If necessary, you can aim normal arrows at the legs of any enemies approaching in front of the main group, to slow them down until the others catch up.
