Hey all!
I've seen a lot of posts on here on getting exit camped on Interchange. I know it's a pain when you are walking to EMERCOM checkpoint with some phat loot, and then some kid with a hunter sitting in a bush kills you.
Here's my tip: bring a REAP-IR with you. How? Stick the DLOC mount on a la rue sight riser, and then stick it in your case for the raid. When you're walking out, switch out your regular sight for your thermal, and scan your surroundings. I find white-hot mode to work the best. If/when you see any white, shoot it. After you've cleared the area, you're safe to extract!
I know thermals can be expensive, but with an added 8k, they're safe in your container for the big fights. Most exit campers are sitting with a wide sight picture in a bush, and focusing in on movement they see. So make sure not to expose yourself too much. This has worked well for me, and teaches those extract campers that they aren't undetectable.
Happy hunting!
