Last Z Military Center Guide — Unit Capacity and Upgrade Timing
Quick Answer
Military Center is the building that increases unit capacity. Upgrade it when the next capacity increase helps your troop training plan, but do not treat it as more important than HQ, Laboratory, troop tier unlocks, or required HQ prerequisite buildings.
Each Military Center upgrade increases unit cap, but the practical value depends on your bottleneck. If you cannot keep training queues active, cannot afford the troops, or still need a bigger HQ/Lab/troop-tier unlock, capacity is useful but not always the next best spend.
When to Upgrade Military Center
Use this order before spending resources on Military Center:
- Open the Military Center upgrade screen and compare your current unit cap with the next level.
- Check whether your training queues are actually capped by capacity, not by resources, speedups, or troop tier.
- If capacity is the bottleneck, upgrade Military Center and refill your training queues.
- If troop tier is the bottleneck, keep pushing the HQ, Laboratory, and research path that unlocks better troops first.
- If an HQ upgrade requires another building right now, follow the HQ prerequisite instead of forcing Military Center out of order.
The clean rule is simple: upgrade Military Center for capacity when capacity is holding back training. Do not upgrade it only because it adds visible power.
Military Center Mistakes to Avoid
- Chasing power only: Military Center can raise displayed power, but power gain is not the same as better troop tier, better research, or stronger formations.
- Assuming a formula: Do not assume power scaling is linear unless the current in-game screen confirms the exact gain for your next level.
- Ignoring troop tiers: More capacity helps, but stronger troop tiers usually matter more once a tier unlock is within reach.
- Upgrading while queues sit idle: Capacity has low value if food, wood, electricity, or speedups are what actually stop your training.
- Forgetting HQ prerequisites: If your next HQ level requires a different building, finish that requirement before treating Military Center as the main blocker.
Military Center Upgrade Checklist
- Check your current Military Center level and the next-level unit cap in-game.
- Look at all troop training queues and confirm whether they are capped by capacity.
- Check whether you are close to a stronger troop tier unlock through HQ, Laboratory, or research.
- Check the next HQ prerequisite building before spending on optional capacity.
- Upgrade Military Center when the new cap will be used immediately or when the building is part of your current progression path.
If the next upgrade will not change your training routine this week, it is usually safe to delay it behind HQ, Lab, troop tier, or event-timed construction value.
