I remember seeing this movie as a kid (so late 80s/early 90s) but it was on VHS so could be slightly older. A man was being hunted by the army in what I remember as a forest or a woodland, and was laying traps to take out the soldiers hunting him down. I’m assuming he was ex-army too, as he was pretty skilled with a hunting knife and explosive putty and tripwire. I also have a vague memory of him scalping one soldier. The film ends with him raising his arms above his head and screaming, which is also the picture on the front of the video box. Can anyone help me with this?
