Project Zomboid's National Guard: What They Left Behind
Project Zomboid National Guard
Complete Guide for Build 41 & 42
Introduction
Welcome to the definitive guide on the National Guard in Project Zomboid's Build 41 and 42. If you're curious about how the military is represented in the game's latest builds, what their role was during the Knox Event, or how to experience military content through official features and mods, you've come to the right place.
We'll explore everything from official lore references in radio broadcasts to military locations on the map, along with the best mods that enhance the National Guard experience. Whether you're a lore enthusiast, a tactical player looking for military gear, or someone wanting to roleplay as the last surviving member of Kentucky's National Guard, this guide covers it all.
Note: No NPCs in B41/42
While the National Guard plays a significant role in Project Zomboid's story, there are currently no living NPC soldiers in Build 41 or 42. The military presence exists through environmental storytelling, zombies in uniform, and lore. NPCs are planned for Build 43 and beyond.
Official Lore: The National Guard & Knox Event
Radio and TV Broadcasts
Project Zomboid tells much of its story through radio and television broadcasts that play during the early days of the outbreak. These broadcasts reveal how the National Guard was deployed to contain what would become known as the Knox Event.
Young men and women who only four days ago were preparing to ship out overseas... but who now, for some unknown reason, have been deployed to guard their very homes. Still no word on conditions inside the Zone...
Other broadcasts reveal a timeline where the National Guard, alongside the U.S. Army, established quarantine zones around Knox County. Initially described as a response to a "chemical leak" or "extreme flu," these broadcasts gradually become more desperate as the situation deteriorates.
Knox Event Timeline
Survivor Broadcasts
Not all radio content comes from official sources. Players who explore radio frequencies might discover "Hal," broadcasting from a hijacked Air National Guard base in Nashville. Initially offering sanctuary, Hal's broadcasts become increasingly distressed before abruptly ending, suggesting a dark fate for this military shelter.
Game World Content in B41/B42
Louisville Border Quarantine Camp
Located at the southern edge of Louisville, this large military checkpoint is one of the most significant locations related to the National Guard in Build 41. It features:
- Multiple Army tents and temporary structures
- Military vehicles and roadblocks on the highway
- Fenced perimeter with guard towers
- Large numbers of zombified military personnel
- High-tier military loot (weapons, ammunition, gear)
This location provides tangible evidence of the National Guard's attempts to maintain the quarantine zone. It's also one of the best places to find military equipment in the vanilla game.
The Secret Military Research Facility
West of Rosewood lies a mysterious military installation often referred to by players as "the secret base." In Build 41, this location consisted of:
- A remote facility deep in the forest, far from roads
- Security fencing and a single large concrete building
- High concentration of zombified scientists and soldiers
- Sparse but valuable loot
Build 42 expanded this location significantly by adding an underground research bunker. This new area contains additional lore clues and better loot, hinting at what the military was researching before the outbreak.
Other Military Presence
Throughout Knox County, you'll encounter other signs of military activity:
- Roadblocks and smaller checkpoints on highways
- Military zombies in uniform (potential source of gear)
- A National Guard armory store in Louisville's mall
- Knox Penitentiary, where lore suggests the military tried to secure the facility
Note that Fort Knox, while mentioned in the lore, is not present on the vanilla map. It would be located south of Muldraugh, but currently exists only in mods.
Build 41 vs Build 42 Changes
| Feature | Build 41 | Build 42 |
|---|---|---|
| Louisville & Checkpoint | Added the city and military quarantine camp | Refined zombie population and loot distribution |
| Secret Military Base | Surface level facility only, minimal loot | Added underground research bunker with more loot and lore |
| Loot Distribution | Static loot placement | "Pre-looted world" system (locations may be partially looted) |
| NPCs | None (zombies only) | None (planned for Build 43+) |
| Military Equipment | Basic military weapons and gear | Expanded selection, improved distribution |
Patch History Timeline
- Build 33 โ Added radios/TV (first lore mentions of National Guard quarantine)
- Build 41 โ Added Louisville map with military checkpoint, secret base (surface level), military loot and zombie spawns
- Build 41.xx โ Various tweaks to military zombie spawns and loot distribution
- Build 42 (IWBUMS) โ Expanded secret base with underground bunker, world loot scarcity simulating prior scavenging
- Future: Build 43+ โ Planned NPCs (potentially including military factions)
The "Pre-looted World" Concept
Build 42 introduced a system where some locations may be found partially looted when you arrive, implying that other survivors (or perhaps the retreating military) have already scavenged supplies. This creates a more dynamic and unpredictable looting experience, especially in high-value areas like military checkpoints.
Modded Content: National Guard in Mods
Expanded Helicopter Events
This popular mod by Shark and ChuckleberryFinn greatly enhances the military presence in the game with various air vehicles:
- Military helicopters (National Guard UH-1 "Huey") that fire on zombies
- FEMA supply drops with valuable resources
- News and police helicopters with different behaviors
- Military jets conducting flybys
- Hostile raider helicopters that attack everything
The mod integrates with the Emergency Broadcast System, providing warnings about incoming air activity. It's one of the best ways to experience the "ghost" of the National Guard's continued operations during the outbreak.
Military Response Mods
Several mods simulate military rescue attempts or operations:
- CDC Rapid Response - Adds medical supply drops, checkpoints, and evidence of military intervention
- Fort Knox - Adds the real-world Army base to the game map
- Military Themed Scenarios - Custom starting scenarios like helicopter crash survival
NPC Mods
While vanilla PZ doesn't have NPCs yet, some mods attempt to add them:
- Superb Survivors - Adds basic AI survivors
- Army NPC Add-ons - Extensions that create military-themed NPCs
Note that NPC mods tend to be experimental and may not work perfectly with all game versions.
Military Gear and Equipment
Brita's Weapon Pack
Adds dozens of military-grade weapons, including M16s, M4A1s, machine guns, sniper rifles, and grenades.
Brita's Armor Pack
Adds tactical gear like ballistic vests, combat helmets, and military uniforms.

Strategies & Gameplay Tips
Looting Military Zones
Go Late, Go Loud
Wait until you're well-equipped, then use vehicles and firearms to clear military zones quickly. The noise will attract zombies, but you'll have the firepower to handle them.
Go Early, Go Stealthy
Visit military locations in the first week, before helicopter events have migrated large hordes. Use stealth to weave between zombie groups and grab high-priority loot.
Key Areas to Check
- Large tents and container crates (often contain weapons)
- Fenced-off sections and "armory" rooms with metal doors
- Military zombie corpses (may carry weapons and armor)
Watch for Alarms!
Some office buildings at military checkpoints have alarm systems. One broken window could attract every zombie in the area. Consider disabling alarms first if you have the skills.
Exit Strategy
Always plan your escape before entering a military zone:
- Park a getaway vehicle at a safe distance
- Leave the driver's side door open for quick entry
- Clear the area around the vehicle beforehand
- In multiplayer, consider having a dedicated getaway driver
Surviving Helicopter Events
If you're using the Expanded Helicopter Events mod, you'll need different strategies for different aircraft:
- Military Helicopters - Take cover if they're firing. They usually target zombies but can hit you by accident.
- Supply Drops - Move quickly to secure dropped crates before zombies converge on the area.
- Hostile Raiders - Hide indoors until they pass. They will shoot at anything that moves.
Monitor the Emergency Broadcast System for warnings about incoming air activity. This gives you time to prepare or seek shelter.
Utilizing Military Gear
Assault Rifles
Fire in short bursts for better accuracy. Consider a suppressor to reduce noise. Great for clearing large groups at medium range.
Body Armor
Protects against bites and scratches to covered areas. Weighs you down but worth it in high-risk situations.
Military Vehicles
More durable than civilian vehicles. Great for transporting large amounts of loot or ramming through zombie hordes.
Roleplay & Challenge Scenarios
"No Hope, No Rescue" Last Stand
Take on the role of National Guard soldiers left behind at the Louisville checkpoint. Your mission: hold the line as long as possible against endless zombie hordes.
Setup:
- Start at the Louisville checkpoint
- Set zombie population to insane (or use sprinters)
- Barricade the camp and set up kill zones
- Venture out daily for supplies
Win Condition: There is none. It's how you die that matters.
"Evacuation to Louisville" Challenge
Race against time to reach the Louisville Army camp for the last evacuation chopper out of Knox County.
Setup:
- Start in a distant town (March Ridge or West Point)
- Day 0 of the outbreak
- Must reach Louisville checkpoint by Day 7 at noon
- Optional: "rescue" NPCs along the way (with mods)
Win Condition: Reach the helipad area at the checkpoint by the deadline.
Multiplayer Roleplay Ideas
In multiplayer servers, players have formed National Guard factions with various roles:
- Military Police - Enforce quarantine rules, detain infected survivors
- Rescue Teams - Conduct missions to extract civilian players from dangerous areas
- Forward Operating Bases - Build and defend military outposts that offer sanctuary to other players
"One of my favorite military-themed runs in PZ was when I decided to recreate '28 Days Later.' I played as a National Guard reservist who missed the evac. For the first month, I moved slow, secured an outpost at the edge of Louisville. I collected guns, built a stockade, even cleared a path into the city.
Then the 'virus mutated' - I changed sandbox settings to make all zombies sprinters. That night, the helicopter event triggered and suddenly I had 100 sprinting zombies at my perimeter. What followed was the most heart-pounding all-night defense ever.
Eventually, they breached my fence. I grabbed my bug-out bag and fought to a modded Humvee in the garage. Peeling out while hordes chased me was pure adrenaline. I spent the next days on the road, looking for a new refuge. That emergent story is what makes PZ so special."
Conclusion & Future Outlook
In Project Zomboid's Build 41 and 42, the National Guard exists primarily through lore, environmental storytelling, and the haunting remains of their last stand. While you won't encounter living soldiers in the vanilla game, their presence is felt everywhere: in abandoned checkpoints, radio broadcasts, and the zombified remains of those who tried to contain the Knox Event.
The developers have confirmed that NPCs are coming in Build 43 and beyond, which may include military factions or organized survivors. Until then, mods like Expanded Helicopter Events and Fort Knox allow players to experience a more active military presence in the apocalypse.
Whether you're raiding the Louisville checkpoint for supplies, roleplaying as the last surviving National Guard member, or building your own military-style base with friends, the National Guard storyline adds depth and purpose to the Project Zomboid experience.
In the end, the National Guard in Knox County serves as a powerful reminder: this isn't just a world that died โ it fought like hell on the way down. That thin olive drab line held as long as it could, and now we โ the players โ inherit both the burden and the tools they left behind.
