10 Most Underrated Military Horror Movies

Military horror is a unique sub-genre that blends the gritty realism of a great war movie with the spine-chilling terror of good supernatural horror. These films delve deep into the psychological trauma of soldiers, the fear of the unknown, and often, the inescapable horrors of battle. With soldiers already experiencing the brutality of battle in the best war movies, the addition of supernatural threats elevates the tension and stakes. This makes these stories even more unnerving.

While many military-themed horror and supernatural films have gained significant attention, there are several that remain underrated and deserve more recognition. These films offer unique perspectives on both war and horror, using atmospheric tension, psychological dread, and supernatural forces to create deeply unsettling narratives. From haunted World War I trenches to eerie Nazi bunkers filled with undead soldiers, these movies have crafted unforgettable moments that stand out within the genre.

1 Deathwatch

Released In 2002

Deathwatch is a great example of how horror and war films can be fused to great effect. Set during the horrors of World War I, Deathwatch follows a group of British soldiers who, after becoming disoriented in a fog-filled battlefield, stumble upon a seemingly abandoned German trench. However, they soon realize that something far more sinister lurks within the trenches. The film masterfully combines the grim reality of war with supernatural horror.

The setting itself, which is muddy, claustrophobic, and labyrinthine, adds to the eerie atmosphere. This reflects the soldiers’ psychological breakdown as they face an unseen force that preys on their fears. Deathwatch is not only a story about survival, but also about the mental toll that war takes on those who fight. With a cast of young British actors including Jamie Bell and Andy Serkis, its slow-burn pacing, and bleak tone, this movie is a hidden gem that deserves more recognition for its unique mix of war drama and horror.

Set against the backdrop of the Mexican-American War, Ravenous is a darkly comic horror film that tells the story of Lt. John Boyd, a disgraced officer who is sent to a remote military outpost. When a man named Colqhoun arrives at the outpost with tales of cannibalism, the soldiers embark on a rescue mission. However, their efforts quickly turns into a nightmare as they’re forced to cross serious moral lines for a chance at survival.

Ravenous expertly blends psychological horror with black humor, focusing on the primal urge to survive — by any means necessary. The use of cannibalism as both a literal and metaphorical element highlights the dehumanizing effects of war. The film’s unsettling atmosphere and unique tone make it a standout in both the war and horror genres. Despite its inventive approach, Ravenous remains underappreciated, often overshadowed by more conventional horror films.

Released In 2002

Set aboard a WWII submarine, Below follows the crew as they begin to experience strange occurrences after picking up survivors from a torpedoed British hospital ship. As tensions rise and paranoia sets in, it becomes clear that something supernatural is haunting the vessel. The film masterfully uses the confined space of the submarine to heighten the tension, creating an almost unbearable sense of claustrophobia. This unique setting for a horror film proves to be an ideal space to keep the narrative character-focused and tense.

The combination of war-time thriller and creepy ghost story makes Below a unique and atmospheric horror film that is both unsettling and suspenseful. Despite its strong concept and execution, the movie remains underappreciated by mainstream audiences. The blend of supernatural horror and wartime drama sets it apart in the military horror genre, and gives fans of both genres plenty of reason to seek it out.
