Mine

[Jones]

This movie gives a very clear depiction of how a trigger to an emotional state and the ensuing reliving of traumatic memories limited the ability of the protagonist to take in direct information that the odds were much better than he thought and that he may have been able to use to reduce his own suffering and possibly even to save the life of his buddy.

Part of the blurb about the movie says:

In the middle of the desert, an area filled with 33 million blast mines scattered everywhere, marine sniper Sergeant Mike Stevens is on a mission to locate and neutralize the leader of a terrorist cell. After three months and six days in the desert, one single moment of hesitation is enough to blow the entire mission, and now Sergeant Stevens is stranded in a hostile guerrilla territory all alone, and to make matters worse, with his left foot on an active mine. Against the harsh environment, without water, the sergeant must stay glued to the spot and use his Marine training, his resourcefulness and his perseverance for the next 52 hours until a convoy arrives in his area. Between the scalding heat of the day and the freezing cold of the night, if Sergeant Stevens wants to survive, he must fight not only the mighty forces of nature but also the greatest adversary of them all: himself.

Being set in the harsh environment of a desert during a war, there is some blood and gore.
