This is a really helpful guide, but I'd like to add a few things.
Firstly, taking long range fights is really useful in surviving, but if you're still early in the game, I'd go for cheap scrap parts and a modern/composite suppressor, mag dumping homemade ammo on unsuspecting enemies. this works well combined with stun and is how you'll want to take down corpos.
Secondly, you're really supposed to know how to use your abilities effectively, especially in the higher difficulties. If you're playing on Easy and even Medium, one FMJ intermediate cartridge to the head will kill your normal scav/raider.
Lastly, Don't be afraid to fight too much. Obviously you shouldn't be spending thousands of bullets like Touhou, but taking those fights and clearing the map/s will reward you with some bad loot up to really good loot. I rarely bought any equipment from traders because I always fought corpos, which are where most spawn in Highway.
If you're a new player who justs wants the sex feature, go god mode and surrender a bunch of times. If you want to play Tarkov, you can download an older version of SPT AKI from repacks. But if you want to play this game, then just have fun with it.
