Last War Drill Ground Guide: Unlock, Best Strategy & more

Hello Players! In Last War: Survival, many players believe heroes are the core of combat power. While heroes are extremely important, veteran players understand that troop capacity and training efficiency are what truly determine long-term strength. This is why the Drill Ground becomes one of the most critical buildings in the entire base. I will show you details about this next.

What Is Last War: Survival Drill Ground?

The Drill Ground is the building responsible for housing your troops. Every soldier trained in Barracks occupies Drill Ground capacity. If capacity is full, troop training stops immediately.

Core Functions of the Drill Ground

Increase Troop Capacity	The higher your Drill Ground level: the more troops you can store, the more troops you can upgrade, the stronger your total power becomes.	Troops contribute a huge percentage of overall power in Last War.
Improve Event Performance	Many major events depend heavily on troop training: VS Duel Arms Race Total Mobilization Unit Progression	Without enough Drill Ground space, event scoring efficiency drops sharply.
Strengthen War Recovery	Large alliances constantly fight: zombie bosses, warzone battles, enemy invasions, PvP wars.	Higher troop capacity means faster rebuilding after losses.

 

How to Unlock Drill Grounds in Last War: Survival?

In Last War: Survival, players can unlock up to 4 Drill Grounds. Each additional Drill Ground significantly increases troop capacity and overall military strength.

Order	Requirement
First Drill Ground	The first Drill Ground is unlocked automatically during the tutorial.
Second Drill Ground	Headquarters Level 16
Third Drill Ground	Headquarters Level 21
Fourth Drill Ground	Complete“Extra Drill Ground” Research inside the“Siege to Seize” Technology Tree. Before unlocking this technology, your Special Forces research progress must reach around 40%.

 

Why the 4th Drill Ground Matters?

The 4th Drill Ground is considered a major late-game milestone.

It increases total troop capacity by roughly one-third compared to having only three Drill Grounds. Competitive alliances usually expect active players to eventually unlock it.

Why Last War Survival Troop Capacity Is Important?

Many beginners underestimate troop capacity because they focus only on hero rarity, gear and technology. However, experienced players know that troop quantity heavily affects sustained combat, event ranking, war endurance and recovery speed.

When Barracks finish training but the Drill Ground has no remaining space, it will lead to training halts, production efficiency collapses and event preparation becomes impossible. This problem becomes especially serious during VS Day. So players need to pay attention!

 

What is Drill Ground Upgrade Strategy?

Stage	Goal	Strategy
Early Game (HQ 1–15)	Build stable troop production Avoid capacity bottlenecks Increase overall power quickly	focus heavily on your first Drill Ground, keep it close to HQ level, do not ignore Barracks upgrades.
Mid Game (HQ 16–24)	The second and third Drill Grounds massively improve: event scoring, troop reserves, recovery speed.	keep Drill Grounds within 1–2 levels of HQ.

 

What Is Troop Ladder Training?

Troop Ladder Training is a method where you train lower-tier troops first, then continuously promote them step-by-step into higher tiers during special scoring events. Instead of directly training T9 or T10 troops from scratch, you gradually upgrade T7 → T8 → T9 → T10 to repeatedly earn event points from the same batch of troops.

The main advantage is efficiency during scoring events like Versus Day, Total Mobilization, Arms Race – Unit Progression, Instead of receiving points once from training troops, you receive points multiple times through promotions.

 

Why Promotion Is Better Than Direct Training?

The biggest reason is time efficiency. Promotion is dramatically faster than training high-tier troops from scratch. That means you can, Finish more troop cycles, Earn more event points, Use speedups more efficiently, Increase ranking potential. Troop Ladder Training is one of the most efficient scoring strategies in Last War. Instead of training expensive high-tier troops directly, smart players repeatedly promote the same troop batch through multiple tiers to maximize event value.

 

What To Do When Drill Grounds Are Full?

Solution	Detail
Upgrade Drill Grounds	The safest long-term solution
Promote Existing Troops	Instead of training new troops，upgrade old troops into higher tiers
Strategic Troop Losses	Some veteran players intentionally lose troops during，zombie fights, doom walkers, PvP battles. This creates additional training space for events.

One advanced mechanic many players forget, Troops inside hospitals do NOT count toward Drill Ground capacity. So you can make use of this mechanic according to different situation.

 

Conclusion

In Last War: Survival, the Drill Ground is far more important than many players initially realize. It directly affects troop capacity, training efficiency, event performance, and long-term combat strength. Players who properly manage troop production, promotions, and Drill Ground upgrades will progress much faster than those who focus only on heroes or technology. Whether you are a casual player or aiming for competitive alliance warfare, maintaining efficient troop management and keeping your Drill Grounds upgraded is one of the most reliable ways to strengthen your account over time.
