Multiple scenes from a movie I cannot remember the title:

• military guy gets hurt and can’t walk. he has to stay behind in a small shack. there’s lots of snow and it’s cold. his teammates – one female and one male tells him they’ll hurry back
• the female teammate attacks the male teammate with like an ax then all of a sudden, a weird human hybrid thing appears (is really fast) comes to attack them
• the guy ends up in a huge fight with the human hybrid and almost dies
• I think the end of the movie the guy comes face-to-face with the military who wants to kill him
