I will say that Warrior difficulty forces you to think smarter and interact more with the environment than you have before. Bad guys will use clearing methods such as grenades, and they will come after you from a great distance provided that they did catch sight of you. I ran down a pirate, but another 2 gusy about 100 meters away came to investigate the crash, and before I knew it, I was fighting 7 guys that had me severely outgunned.

For example, when I was playing on Warrior difficulty level, I crashed into a ditch near Amanaki at X:416.3, Y:771.6. On normal or harder enemies will investigate gunshots they hear in the distance. But this is mostly about group behaviour. You take a lot more damage on higher difficulties, 1-2 gunshots will take away a bar of health, most animal attacks will take away 1 bar of health, bigger animals (tigers etc) can kill you very easily and falling damage is more realistic. The bad guys will detect you more easily, and they will be smarter about where to look if they know something is going on. Warrior mode allows for 2 shots before you lose a health bar. They will not have more hit points, but they will deal more damage in the sense that you take more damage. Their numbers are constant: same 2-man patrols but enemies nearby will come to reinforce them quickly if they are within earshot and hear fighting.
