Remove Detection and Hit sounds from game  

Since another person managed to make the crossbow invisible, I decided to find a similar solution to remove that detection noise from the game - that alarm that beeps when enemies are about to spot you, before they start shooting. It's possible that I removed other sounds in the process.

I'm not responsible for anyone corrupting their game or any other damage to system files, do it by your own risk.
I'm also not providing further explanations, you can find more help about the tools here described in the internet.

There are 2 ways to do it:

Use my files lazy way:
1. Download the rar file
2. While it downloads locate the folder "Tom Clancy's Ghost Recon Wildlands\sounddata\pc"
3. Make a backup of "sounds_sfx.pck" and "sounds_sfx_patch_1_.pck"
3. Place the files from the rar into this folder
4. Enjoy realistic enemy fight.

Do it yourself complicated way:

1. Use Wwise-Unpacker to extract the .pck files - I had to duplicate and edit the .bat files to keep the .wav originals (downloaded from this site https://www.reddit.com/r/forhonor/comments/5t0rrx/hey_guys_here_is_a_small_tutorial_on_how_to/ )
2. Listen to the converted files until you identify the sounds you want to remove
3. Open the .pck in HEX editor (I used HxD)
4. Open the .wav version of the sound also in HEX editor
5. Copy the HEX data from .wav (without the header) and search it in the .pck
6. Replace that data with zeros.
7. Repeat for the other sounds.
