For Last Z players who are spending on hero packs and still losing battles. The answer is usually troop alignment, not more heroes.
In Last Z: Survival Shooter, heroes set the direction but troops deliver the outcome. The troop types you train, how they align with your hero faction, and how efficiently you manage your army between events determines your real competitive position. Not just your hero roster.
This guide covers every Last Z troop type, unit special training in full detail, the faction-to-troop matching system that serious players build around, troop load, formation strategy, and how to manage your army without wasting training resources.
Last Z troop guide (what serious accounts build around)
Last Z has three troop types: Assaulters, Shooters, and Riders. Each is trained at a corresponding camp, tied to a specific hero faction, and part of a counter triangle that determines which formation wins the matchup regardless of power score. Assaulters are the Blood Rose troop type, Shooters are Wings of Dawn, and Riders are Guard of Order.
Unit special training is a separate enhancement layer on top of base troop tier stats. It is accessed through the camp building menu for your primary troop type, costs camp-specific training resources, and stacks directly on top of your base tier bonuses. The return is significant at T9 and above. Investing in unit special training on your primary troop type is one of the highest-return moves available to accounts spending consistently. It produces a stat advantage that does not appear in the power score but shows up directly in how long formations survive contact.
The most important decision in Last Z troop investment is committing to one troop type completely. Splitting training resources across all three types fragments every hero bonus, every research buff, every camp upgrade, and every unit special training investment that would otherwise stack into a single compounding advantage. Serious accounts pick one faction, build one camp to the highest tier accessible, and push that troop type to T9 and beyond.
Last Z best formation (mono-faction, mono-troop-type)
The best formation in Last Z is not the one with your five highest-power heroes. It is the one where every hero buffs the same troop type, every troop in the march is the same type, and every research bonus, camp upgrade, and hero passive stacks into a single compounding layer.
Hero skill bonuses that say "troop led" apply only to the units in that hero's specific formation. A Blood Rose hero leading Shooters produces zero Assaulter bonus from their skills, even if those skills say "Assaulter HP +15%." Mixed formations feel balanced on paper but perform below their power score in every engagement because multiple bonus stacks are only partially active.
The exception is heroes whose passives say "regardless of deployment." Selena's passive applies 45% Assaulter defense to every Assaulter formation on the account whether she is deployed in that formation or not. This is the single most important distinction in Last Z troop strategy: identifying which heroes have army-wide passive bonuses and maxing those heroes first. Their value does not depend on which formation they lead. It applies the moment they are built.
For serious spenders: pick one faction, max the corresponding camp as your first camp priority, push exclusively to T9+ in that troop type, and ensure every hero in your primary formation buffs the same unit type.
Last Z unit special training (how it works and when to invest)
Unit special training is one of the most searched systems in Last Z and one of the most misunderstood. Players who find it early invest in the wrong troop tier. Players who find it late leave a significant stat advantage on the table for months.
Unit special training is accessed directly through your camp building. Tap your primary camp, whether that is the Assaulter Camp, the Shooter Camp, or the Rider Camp depending on your faction, and the unit special training option appears as a separate menu within the camp interface. It is not in the research tree and not in the hero menu. It is camp-specific.
The system lets you enhance specific troop tiers beyond their base stats by investing camp-specific training resources. These resources are distinct from standard training materials. They are earned through event rewards, specific store purchases in the weekly rotation, and dedicated training events that cycle on the calendar. The enhancement adds stat multipliers that stack directly on top of the base tier bonus.
At T9 and above, a troop with maxed unit special training outperforms the same tier without it by a margin that shows up in sustained combat. Formation survivability increases, damage output per engagement increases, and the time your formation holds under pressure extends meaningfully.
The sequencing rule is the same as every other troop investment: invest unit special training resources only in your primary troop type, only in the tier you are actively fielding at scale. Special training a tier you are about to retire wastes the resource entirely, and the resources are not transferable between tiers or troop types. The worst version of this mistake is maxing unit special training on a T7 or T8 troop tier right before you unlock T9. Every resource spent there is a resource that cannot be applied to the tier you actually need to compete.
Reach T9 in your primary troop type first, then begin unit special training investment on that tier. Camp upgrades that push your troop tier ceiling should always come before unit special training investment. Once T9 is your active tier and your camp is upgraded to sustain it, stacking unit special training on top of T9 base stats is when the return becomes significant enough to feel in competitive content. The combination of highest available tier plus maxed unit special training is what produces the stat gap that separates formations at the same power score level.
Troop load, training speed, and army management...
Troop load is the maximum number of troops a march can carry. It is determined by camp level and by specific research nodes in the Elite Troops and Allied Troops trees. The Last Z research guide covers which nodes to prioritize and in what order. Higher troop load means larger effective marches in kill events, Alliance Duel, and resource operations, which compounds into higher event scores across every activity where march size determines how many points you generate.
Training speed determines how quickly your formation rebuilds after losses. The primary training speed investments are the Elite Troops research tree, which provides universal training speed bonuses across all three troop types with zero badge cost, and early-stage infrastructure heroes whose third skills add training speed before orange heroes take over.
Retraining after every kill event is not optional for competitive accounts. Troop losses in Enemy Buster, State Ruler, and PvP engagements are expected at the competitive level. The discipline is in the loop: lose troops, retrain immediately, maintain army size between events. Accounts that let training queues idle after kill events slowly erode their effective march size relative to servers that retrain consistently.
Hospital capacity, upgraded through the Fully Armed Alliance research tree, determines how many troops can be saved after heavy losses rather than dying outright. That directly affects how much retraining your Gold Bar investment needs to cover after each event.
The camp upgrade priority is straightforward. Your faction's primary camp should always be the highest-priority camp upgrade. Upgrading non-primary camps first delays your troop tier ceiling and slows the entire progression curve. Promoting troops across all three types simultaneously fragments your resources. Commit to your faction's primary troop type and push that tier as high as your camps and research allow. Everything else waits.
Last Z troop investment (the sequencing that actually compounds)
Camp upgrades, unit special training, hero packs, and research all feed into the same formation. The sequence matters as much as the volume of spending behind it. Accounts that invest in the right troop type through the right systems in the right order reach the T9+ competitive floor faster than accounts spending the same amount reactively across all three troop types simultaneously.
The formation that wins isn't the most expensive one. It's the most aligned one. Camp upgrades, unit special training, and T9+ troop promotion require sustained Gold Bar investment on a consistent schedule.

Last Z troop guide: FAQs...
What is unit special training in Last Z?
Unit special training is a stat enhancement system accessed through your primary camp building menu, not the research tree. It adds multipliers on top of base troop tier stats using camp-specific training resources. Reach T9 in your primary troop type first, then begin unit special training investment on that tier. Resources are not transferable between tiers, so investing in a tier you are about to retire wastes them entirely.
What are the Last Z troop types?
Three: Assaulters (Blood Rose faction), Shooters (Wings of Dawn faction), and Riders (Guard of Order faction). Each is trained at a corresponding camp building and has multiple tiers that unlock as the camp levels up. T9 and above is where serious accounts focus their training investment.
What is the best formation in Last Z: Survival Shooter?
A mono-faction, mono-troop-type formation where every hero in the lineup buffs the same unit type and every troop in the march matches that type. Mixed formations underperform their power score because multiple bonus stacks are only partially active. Heroes with "regardless of deployment" passives deliver their bonus across every formation on the account. Identify and max these heroes first.
What does troop load mean in Last Z?
The maximum number of troops a march can carry. Increased through camp level upgrades and specific nodes in the Elite Troops and Allied Troops research trees. Higher troop load produces larger effective marches in events and PvP operations, which directly affects kill event scores and Alliance Duel performance.
What is the Last Z faction counter triangle?
Blood Rose (Assaulters) counters Wings of Dawn (Shooters). Wings of Dawn (Shooters) counters Guard of Order (Riders). Guard of Order (Riders) counters Blood Rose (Assaulters). A well-built counter formation can beat a higher-power opponent running the wrong troop type for the matchup.
